Explanation:
Molarity is defined as the number of moles per liter of solution.
Mathematically, Molarity =
Since it is given that the molarity of a solution of 14.0 g and volume is 150 mL or 0.15 L.
Whereas number of moles =
So, molar mass of
is 97.94 g/mol.
Thus, number of moles =
= 0.142 mol
Therefore, calculate the molarity as follows.
Molarity =
=
= 0.946 mol/L
Hence, we can conclude that molarity of the solution is 0.946 mol/L.
