Answer:

0.0125 mol.

Explanation:

<em>Molarity of a solution is the no. of moles of a solute per 1.0 L of the solution.</em>

<em></em>

M of HCl = 0.5 mol/L.

V = 25.0 mL = 0.025 L.

<em>∴ no. of moles of HCl present in the flask at this time = MV</em> = (0.5 mol/L)(0.025 L) = <em>0.0125 mol.</em>
