Question

A solution contains 30 g of glucose in 500 ml of water. Calculate the
mass by volume percentage of solution.

Answer 1

Given mass of glucose = 30 g
Given volume of water = 500 mL
Density of water = 1 g mL^-1

$Mass=Density\times Volume$
$$\begin{gathered} Mass\%=\frac{Givenmassofsolute}{Givenmassofsolution}\times 100 \\ Mass\%=\frac{30}{500+\hspace{0.17em}30}\times 100=5.66\% \end{gathered}$$
