Question

12) 250 ml of glucose solution contains 18.016 g of solute. what is the molarity of the solution? (MW glucose 180.16 g/mol)

Answer 1

Answer #1

180.16 gm glucose in 1000ml solvent = 1 molar

180.16 gm glucose in 250ml solvent= 1000/250 = 4 molar

18.160 gm glucose in 250 ml solvent = (4 × 18.160)/180.16

= 0.4032 molar
