Question

. Calculate the concentration of the following solutions:

a. mass percent (m/m) for the solute: 75 g of Na₂SO₄ and 175 g of H₂O

b. mass/volume percent (m/v) for the solute: 54 g of KCl in 325 mL of KCl solution

Answer 1

Answer #1

A) Total mass of solution = 75 + 175 = 250 g

(m/m) % concentration = 75*100/250 = 30 % ....Answer

B)

(m/V) % concentration = 54 * 100 / 325 = 16.62 % ....Answer
