6.84 ~g of sucrose is dissolved in 200 ~g of water. The molality of the solution is

Options

  1. A0.2 M
  2. B0.3 M
  3. C0.1 M
  4. D0.02 M

Correct answer

C. 0.1 M

Step-by-step solution

Molar mass of sucrose ( C ₁₂ H ₂₂ O ₁₁ )=342 Molality = Meight of sucrose Molar mass of sucrose Mass of solvent (g) 1000= 6.84 1000 342 200 =0.1 M
