Mass Chemistry

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?

 

? = g sucrose

Answer 1

Answered before. Don't know what happened to that answer.

32% of 905 = 0.32 x 905 = 289.6 g sucrose

Dissolving 290. grams of sucrose in a total volume of 905 ml will produce a solution that is 32.0% sucrose (w/v; m/v).
