1.

Answer 2

The molarity of the solution is 0.5 M. (Option c)

Given:

A solution containing 1.25 mol of HCl

Quantity of solution = 2.5 litres

To Find:

The molarity of the solution

Solution:

We can simply solve this problem by using the following mathematical process.

"Molarity or molar concentration is the number of moles of solute per litre of the solution"

It can be calculated using the following equation

Molarity = Mol solute / Quantity of solution

It is given that the solution contains 1.25 mol of HCl and the quantity of solution is 2.5 l

Therefore, putting the values in the formula we get,

Molarity = $\frac{1.25}{2.5}$

0.5 M

Hence, the molarity of the solution is 0.5 M.
