0.1 mol HCl is equal to

Options

  1. A3.65 g
  2. B36.5 g
  3. C18 g
  4. D1.8 g

Correct answer

A. 3.65 g

Step-by-step solution

Molecular mass of HCl =35.5 (at. wt. of chlorine)+1 (at. wt. of hydrogen) =36.5 As 1 mole is the amount of the substance which has mass equal to gram molecular mass. 1 ~mol HCl is equal to 36.5 g . and 0.1 mole HCl is equal to 3.65 g
