How much water must be added to 40 ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
How much solvent must you add to 1 ml of a 50 percent solution to make a 10 percent solution?
To make a 10 percent solution, you would need to dilute the 50 percent solution by adding 4 ml of solvent to 1 ml of the 50 percent solution. This will result in a total volume of 5 ml with a 10 percent concentration.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
What is the concentration as percent of a solution which contains 160 g of solute in 2.75L of solution?
The answer is 5,82 %.
1 percent solution of a medication equals how many micrograms?
A 1 percent solution of a medication means it contains 1 gram of the medication in 100 mL of solution. To convert grams to micrograms, you multiply by 1,000,000. Therefore, a 1 percent solution would contain 1,000,000 micrograms of the medication.
A chemist needs 90 milliliters of a 77 percent solution but has only 75 percent and 84 percent solutions available Find how many milliliters of each that should be mixed to get the desired solution?
Let v be the capacity in milliliters of the 75% solution required then (90 - v) is the required capacity of the 84% solution needed. 75/100v + 84/100(90 - v) = 77/100 x 90 75v + 84(90 - v) = 77 x 90 75v + 7560 - 84v = 6930 9v = 7560 - 6930 = 630 v = 70 : therefore (90 - v) = 20 The mixed solution requires 70ml of the 75% solution and 20ml of the 84% solution to create 90ml of 77% solution.
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution How much of the 20 percent solution did the pharmacist use in the mixture?
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).
If the required reserve ratio is 20 percent and a customer deposited 5000 in the bank how much is available to the bank for lending?
If the required reserve ratio is 20 percent, the bank must keep 20 percent of the $5,000 deposit as reserves. This means the bank must hold $1,000 in reserve, leaving $4,000 available for lending.

Percents are often used to show the strength of solutions Which solution is stronger the 2 percent or the 3 percent?
A 3 percent solution is 1.5 times as strong as a 2 percent solution.
