Question

80 g of Urea (GMM = 60) dissolved in 1000 g of water gave a solution of density 1.2 g/ml. Calculate the molarity.

Answer 1

Molarity is the moles of solute dissolved per litre of solution
here volume = mass/density
= 1000/1.2
80 gm urea = 80/60 moles
,= 4/3 moles
molarity = {moles / volume(ml) } × 1000
={ (4/3)/ (1000/1.2) } × 1000
= (4/3) × (1.2/1000) × 1000
= 1.6 M
