Answer 2

ANSWER :

Given :

▪ Weight of urea = 10g

▪ Weight of water = 90g

To Find :

▪ Weight percentage of urea solution.

Weight percentage :

✏ Symbol : %(w/W)

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

✏ Effect of temperature : No effect

✏ Formula :

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

๏ Solute = Urea

๏ Solvent = Water

Calculation :

→ %w/W = 10×100/(10+90)

→ %w/W = 1000/100

→ %w/W = 10%
