<u>Answer: </u>0.0285 moles of HCl is present in given amount of solution.
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Molarity of HCl = 0.453 M
Volume of solution = 62.85 mL
Putting values in equation 1, we get:

Hence, 0.0285 moles of HCl is present in given amount of solution.
