Molarity = Moles of Solution / Liters of the solution

First, you need to find the moles of KCl for #1. There is 74.5513 g/mol in KCl.

With that,

19.82 / 74.5513 = 0.2659 moles KCl

          0.2659

1. M = -------------      = 0.05318. Rounded w SF, you get 0.05 M

               5

2. 102.1 / 342.3 = 0.2983 moles C12H22O11

M = 0.2983 / 23.15 = 0.0129 M
