Question

1. The stearic acid/hexane solution contains 0.1 g of stearic acid per 1 mL of solution. What is the molarity of this solution?

Answer 1

Answer #1

Molarity is number of moles of solute present in 1 litre of solution.

molar mass of stearic acid = 284.48 g / mol

moles of stearic acid = 0.1 gm / 284.48 g mol^{—1 =} 3.51x 10^–4mol

molarity = mol / volume ( litre ) = 3.51x 10^-4 mol / 10^-3 litre = 0.351 M
