A solution of glucose in water is labelled as 10 p e r c e n t W W . If the density of the solution is 1.2 g m L - 1 , then what shall be the molarity of the solution?

Question

A solution of glucose in water is labelled as 10 p e r c e n t W W . If the density of the solution is 1.2 g m L - 1 , then what shall be the molarity of the solution?, 0.17 M, 0.67 M, 0.6 M, 0.76 M

mol of glucose =180 10 % W W solution of glucose means 100 g solution contains 10 g glucose. Molarity = moles of solute volume of solution ( mL ) × 1000 = 10 180 100 1 . 2 × 1000 M = 10 × 1 . 2 × 1000 180 × 100 = 0 . 67 M
