Question

if 11gm of oxalic acid are dissolved in 500ml of solution (density - 1.1g/ml) what is the mass percentage of oxalic acid in solution? ​

Answer 1

Answer:

Mass of Oxalic acid (solute) = 11g

Mass of Solution = 500ml

Density = 1.1 g/ml

We know that

Mass % of solute =

Mass of solution =

$Volume \: of \: solution \: × \: Density \: of \: solution$

Mass of solution =

$500×1.1=50×11g$

Mass % of the solute =

$11×50 \div </p><p>11×100$

$=2%$
