mass of solute = 2gm
mass of solution = mass of solute + mass of solvent
= 2gm + 18gm
= 20gm
mass percentage = (mass of solute / mass of solution) × 100
= (2 × 100) / 20
= 10%

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%
