Question

How many moles of HCl are there in 75.0 mL of 0.325 M HCI?​

Answer 1

Answer: The moles of HCl are 0.0244

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute = ?

$V_s$ = volume of solution in ml

Now put all the given values in the formula of molality, we get

$0.325=\frac{moles\times 1000}{75.0}$

$moles=0.0244$

Therefore, the moles of HCl are 0.0244
