What is the molarity of H ₂ SO ₄ solution that has a density of 1.84 ~g / cc at 35^ C and contains 98 % by weight?

Options

  1. A4.18 M
  2. B8.14 M
  3. C18.4 M
  4. D18 M

Correct answer

C. 18.4 M

Step-by-step solution

Molarity = wt. of solute mol. wt. 1000 vol. of solution (in mL) (Volume of solution = mass density = 100 1.84 =54.34 ~mL ) Now, molarity = 98 98 1000 54.34 =18.4 M
