40 % by weight solution will contain how much mass of the solute in 1 L solution, density of the solution is 1.2 ~g / mL ?

Options

  1. A480 g
  2. B48 g
  3. C38 g
  4. D380 g

Correct answer

A. 480 g

Step-by-step solution

aligned & Molarity = solution 10( in litre ) molecular weight of the solute & Molarity = 40 1.2 10 M 1000 aligned Again, since Molarity = weight of the solute / M volume of the solution (in litre) Therefore, weight of solute =480 ~g
