Answer: True
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
[tex]Molarity=\frac{n}{V_s}[/tex]
where,
n= moles of solute
[tex]Moles=\frac{\text{Given mass} of solute}{\text{Molar mass of the solute}}[/tex]
[tex]V_s[/tex] = volume of solution in L
[tex]Molarity=\frac{\text {given mass of solute}}[\text {molecular mass of solute} times V_s}[/tex]
Thus when making a molar liquid solution from a dry chemical stock you must know the molecular weight of the compound.
