Question

40percent by weight of solution will contain how much mass of the solute in 1l solution

Answer 1

Mass % of the solution = 40 %(w/w)

Converting 1 L solution to mass:

Density of solution = 1.2 g/mL

Mass of solution =1 L×$\frac{1000mL}{1L}$×$\frac{1.2 g}{ 1mL}$

= 1200 g solution

Mass of solute = $1200 g solution * \frac{40 g solute}{100 g solution} </p><p> =480 g solute$
