Unless instructions specify otherwise, you can usually assume that a 20 percent sugar solution means 20g of sugar, a measurement of weight, for every 100 milliliters of water, a measure of volume, especially if you’re mixing the solution for use in biology or physiology.

What is the volume of a 25% methyl solution that contains 20 mL of metal?

Answer: Because % is per hundred and 4 × 25 = 100 and there is 25% of methyl that is 20mL ,therefore 4 × 20 = 80.

How do I calculate the concentration of a solution?

Rearranging the equation for concentration allows the mass of solute to be calculated:

  1. mass of solute in g = concentration in g/dm 3 × volume in dm 3
  2. A solution of sodium chloride has a concentration of 10 g/dm 3. …
  3. mass of solute in g = concentration in g/dm 3 × volume in dm 3
  4. = 10 g/dm 3 × 2 dm 3

What is a 10% solution?

A percent solution simply means parts per hundred. For example by weight: A 10% solution by weight simply means that you have 10 grams of compound dissolved in 100 mL of solution. For an example by volume: A 23% solution by volume simply means that you have 23 mL of liquid compound in every 100 mL of solution.
