What is the volume of solution when adding water and ethanol?
However, when mixing miscible liquids (such as water and ethanol), the final volume of solution is not exactly equal to the sum of the individual volumes. For example, adding 50 mL of ethanol to 50 mL of water will result in a total volume that is less than 100 mL. It is actually closer to 96 mL.
How do I calculate the volume of an acid with water?
Since you started with 10.0 mL you would need to add 110 mL to bring the total volume to 120. M1*C1=M2*C2, 10mL*6M=x*.5M, find x, then susbtract from x the initial volume of the acid, to find thevolume of water added. Good luck! Does proper digestion control diabetes? Yes!
What is the volume times the molarity given?
The volume times the molarity given has to equal the volume times the molarity sought ?mL = 120. Since you started with 10.0 mL you would need to add 110 mL to bring the total volume to 120. M1*C1=M2*C2, 10mL*6M=x*.5M, find x, then susbtract from x the initial volume of the acid, to find thevolume of water added.
What is the volume of solution in dilution equation?
Thus , volume of solution should be 0.12L = 120 ml. We can set these equal in a dilution equation because Molarity is Miles per Volume, and by multiplying it by Volume we get Moles on each side. Moles of solute remain equal throughout a dilution since you are just adding water.
How would you make a total volume of 10 ml of a 1 2 dilution of a solution?

How do you make a 12.5 dextrose solution?
To prepare 100 ml of 12.5% dextrose, add 5x12. 5-25=37.5ml of 25% dextrose to 62.5 ml (100-37.5) of 5% dextrose.

How do you calculate dextrose solution?
Multiply the grams of dextrose by 3.4 (there are 3.4 kcal/g dextrose) to determine kcalories supplied by dextrose in a day. Note: If the total dextrose volume is not stated in the prescription, you can calculate it. Just multiply the rate of infusion of dextrose by 24 hr.
How much drug should be used in preparing 50 mL of a solution such that 5 mL diluted to 500 mL will yield a 1 1000 solution?
that 5 mL diluted to 500 mL will yield a 1: 1000 solution? X = 5 g of drug needed to prepare 50 mL of solution Page 19 Page 20 Example 4: How many grams of sodium chloride should be used in preparing 500 mL of a stock solution such that 50 mL diluted to 1000 mL will yield 0.3% w/v solution for irrigation?
How do you calculate IV concentration?
To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.
How do you calculate fluid volume deficit?
Background: The water-deficit equation {WD(1) = 0.6 × B(m) × [1 - (140 ÷ Na(+))]; B(m) denotes body mass} is used in medicine and nutrition to estimate the volume (L) of water required to correct dehydration during the initial stages of fluid-replacement therapy.
How do you calculate fluid requirement?
The Holliday-Segar nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows:100 ml/kg for the 1st 10 kg of wt.50 ml/kg for the 2nd 10 kg of wt.20 ml/kg for the remaining wt.
How do you calculate fluid?
Formulas Used:For 0 - 10 kg = weight (kg) x 100 mL/kg/day.For 10-20 kg = 1000 mL + [weight (kg) x 50 ml/kg/day]For > 20 kg = 1500 mL + [weight (kg) x 20 ml/kg/day]
What does volume times the molarity given have to equal?
The volume times the molarity given has to equal the volume times the molarity sought
How much HCl to add to 2L?
So, take a volumetric flask of 2L and pour 250 mL 4.0 M HCl, then add water up to the 2L mark. Your 2 L 0.5 M HCl solution is ready.
How many moles of HCl are in a liter of HCl?
A 0.1 M solution of HCl has 0.1 moles/L. So for 1 liter of solution, you need 0.1 moles of HCl.
How many moles of HCl are present in 1000 ml of solution?
6.00M HCl means 6 moles of HCl are present in 1000 ml of its solution.
Why do moles of solute remain equal throughout a dilution?
Moles of solute remain equal throughout a dilution since you are just adding water.
How much con HCl to 991.67 ml?
But remember from above: This is for 1 L of solution, so you need to dilute that 8.33 mL of con HCL up to a total volume of 1 liter (meaning you add the 8.33 mL con HCl to 991.67 mL water.)
What equation is used to do serial dilution?
If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.
Why is it better to prepare a percent solution as a weight/weight solution?
For example, if the percent solution under consideration is to be used at widely different temperatures, then it is better to prepare the solution as a weight/weight % solution because its concentration would be independent of variations in ambient temperature.
What does weight mean in chemistry?
1) (Eq. 2) (Eq. 3) As noted above, weight refers to mass (i.e., measured on a balance). When examining the equation for each of the percent solutions above, it is very important to note that in all cases the denominator refers to the solution mass or volume and not just the solvent mass or volume.
Is weight % mass or volume?
An important note is in order. Here, we have used "weight" instead of "mass" simply to be consistent with tradition and popular use. Thus, weight/volume % solutions should be correctly referred to as mass/volume %. Similarly, weight/weight % solutions should be referred to as mass/mass %, or simply mass %.
How many salts are in 50 ml of water?
If the solution contains 15 g salt in 100 g solution, there are 7.5 g salt in 50 mL solution. This assumes that the density of the solution is essentially still the density of water (1 g/mL).
How to find the percentage of salt in a solution?
The percentage of salt in solution is the ratio of the mass of salt to the mass of the solution. Therefore, you will add some mass of pure salt to 250.0 grams of water. Let x = the mass of the salt in grams that you’re adding. The mass of the solution then becomes 250.0 + x.
How much salt is in 50 g of solution?
At the end of 3 days there are 10 g of salt in 50 g of solution.
