A solution contains 2.00 g solute in 100.0 g solution. What is the mass percent of solute?

Explanation:
Mass percent measures how much of the total solution mass is the solute, calculated as (mass of solute / mass of solution) × 100%. Here the solute mass is 2.00 g and the total mass of the solution is 100.0 g. So 2.00 g ÷ 100.0 g = 0.020, and multiplying by 100% gives 2.00%. Therefore the solution is 2.00% solute by mass.
