Answer 2

Answer : The correct option is, (3) 3.0 moles of HCl per liter of solution

Explanation :

Molarity : It is defined as the number of moles of solute present in one liter of the solution. The S.I unit of molarity is mole per liter.

It is represented as,

$Molarity=\frac{\text{Moles of solute}}{V_{solution}(L)}$

where,

V = volume of solution in liter

As we are given 3.0 M HCl(aq) solution this means that 3.0 moles of HCl present in one liter of solution.

Hence, a 3.0 M HCl(aq) solution contains a total of 3.0 moles of HCl per liter of solution.
