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%
