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 795 ml of a 40.0% (w/v) sucrose solution?

Answer 1

Mass of sucrose is 318 grams

$\% \mathrm{~m} / \mathrm{V}=\frac{\text { Mass of sucrose }}{\text { Volume of solution }}$

$\text { Let } m=\text { mass of sucrose }$

$\frac{40.0 \mathrm{~g}}{100 \mathrm{~mL}}=\frac{m}{795 \mathrm{~mL}}$

$m=\frac{40.0 \mathrm{~g} \times 795}{100}$

   = 378 g
