So, the mass per cent of Solute = 10 %.

Mass percent of solute =

mass of solution

mass of solute

×100

Mass of solute = 2 g

Mass of solvent = 18 g

Mass of solution = 20 g

∴ Mass percent of solute =

20

2

×100

=10%

Answer 2

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% .
