Given :

▪ Mass of urea = 5g

▪ Mass of water = 95g

To Find :

▪ Mass by mass percentage of urea in solution.

Mass Percentage :

Definition : Amount of solute in grams present in 100g of solution.

Symbol : %w/W

Effect of temperature : No effect

Formula :

%w/W = [(Mass of solute) ÷ (Total mass of solution)] × 100

Calculation :

▪ Mass of solute = 5g

▪ Total mass of solution = 100g

→ %w/W = 5/100 × 100

→ %w/W = 500/100

%w/W = 5%
