Mass of a Solute

Question

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 905 mL of a 32.0% (w/v) sucrose solution?

Answer 1

32% of 905 = 0.32 x 905 = 289.6

So, 289.6 g in a total volume of 905 ml is a 32% (w/v or m/v) solution.
