Question

A solution have mass $250gm$ and concentration $10$%. Find amount of the mass of solute present in a solution.

Answer 1

Mass % of solution = $(massofsolute\times 100)/massofsolution$

$10=massofsolute\times 100/250$

$massofsolute=10\times 250/100$

$massofsolute=25gm$

Amount of mass of solute present in solution is $25gm$.
