Moles of HCl = 0.282
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
[tex]\large \boxed {\bold {M ~ = ~ \dfrac {n} {V}}}[/tex]
Where
M = Molarity
n = number of moles of solute
V = Volume of solution
The volume of HCl=62.2 ml=0.0622 L
The molarity of HCl = 4.54 M
Then moles of HCl :
[tex]\tt n=M\times V\\\\n=4.54\times 0.0622\\\\n=0.282~moles[/tex]
