Take 100 grams of 5% solution and do one of the following:
- Mix 95 g of it with 5 grams of sugar to end up with 100 g of 10% solution,
or, when you are short of sugar:
- Evaporate 50 grams of water from 100 g of the 5% solution to end up with 50 g of 10% solution.

Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
How do you make 50 percent to 20 percent solution?
Add an 0.4 L of solvent to 0.6 L solvent: 50% * 0.4 L = 20% * (0.4 +0.6) L
How do you dilute 31.45 percent hydrochloric acid to a 20 percent solution?
Add 57.25 g of water to 100 g of 31.45%HCl solution,because [(31.45/20)*100]-100 = 57.25 g
What is the molarity of 10 moles of salt dissolved in 20 liters of water?
Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------
What is the specific heat of 10 percent sulfuric acid?
For any acid solution the specific heat can be arrived by weight average basis. For a 10% acid the sp.heat will be 0.1 * 0.345 Btu/lb F + 0.9 * 1.0 = 0.9345 Btu/lbF Specific heat of 10% Sulfuric acid is 0.9345 Btu/lb F or 3.9126 kJ/kgK
How many ounces of 20 percent saline solution must be added to 40 ounces of a 5 percent saline solution to make a 10 percent saline solution?
NOT: 15 ounces to make 10%Correct answer:Twenty ouncesCalculus:Let it be M ounces. Then:20%*(M ounce) + 5%*(40 ounce) = 10%*(M+40 ounce)20*M + 200 = 10*M + 400(20-10)*M = 400-20010M = 200M = 20

10 gallons..
How many liters of a 20 percent solution of acid should be added to 10 liters of a 30 percent solution of acid to obtain a 25 percent solution?
10 liters.
How many liters of a 20 percent solution of saline should a nurse mix with 10 liters of a 50 percent solution to obtain a mixture that is 40 percent saline?
Let x = the amount of 20% solution Let x + 10 = the amount of the final solution. So we have: (.20)x + (.50)(10) = (.40)(x + 10) .20x + 5 = .40x + 4 .20x = 1 x = 5 liters of 20% solution of saline.
If a 10 percent sugar solution is separated from 20 percent sugar solution by a selectively permeable membrane in which direction will there be net movement?
The direction will be towards the more concentrated side so the 10% solution with go towards the 20% solution in an attempt to reach equilibrium.

What is half of 20?
Half of 20 is 10. If you add 10 and 10, you will see that they make 20. Since they are both the same number and equal to 20, then 10 is half of 20.
How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
