Answer 2

Correct Question :

solution is prepared by adding 2g of a substance a to 18 of water. calculate the mass percentage of solute

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%
