Answer :
Mass of solute = 2g
mass of solvent = 18g
we need to find the mass Percent of solute
Mass % of solute = Mass of solute/mass of Solution × 100
Mass of solute = 2g
Mass of Solution = 2g + 18g
Mass of Solution = 20g
Mass % of solute = 2g/20g × 100
= 2 × 5
= 10%
Hence,
- Mass percent of solute is 10%
