Question

What volume of 0.686 M HCl would contain 0.037 moles of solute?

Answer 1

Given :

Molarity of HCl solution, M = 0.686 M.

Number of moles, n = 0.037 moles.

To Find :

The volume of solution.

Solution :

We know, molarity is given by :

`M = (Number \ of \ moles \ of \ solute)/(Volume \ in \ liter)\\\\0.686 = (0.037)/(V)\\\\V = (0.037)/(0.686)\ L\\\\V = 0.053935 \ L \\\\V = 53.94 \ ml`

Hence, this is the required solution.
