The relation between molarity and normality is expresses as: a) M = N x g.e.w/g.m.w
b) M = N x g.m.w/ g.e.w
c) M = N x no. of equiv./mole
d) M = N x no. of g.m.w/mole

Answer: [tex]Molarity=Normality\times \frac{gew}{gmw}[/tex]

Explanation:

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

[tex]Molarity=\frac{\text {moles of solute}}{\text {Volume in L}}[/tex]

[tex]{\text {moles of solute}=\frac{\text {given mass}}{\text {Molar mass}}[/tex]  

Normality is defined as the number of gram equivalents dissolved per liter of the solution.

[tex]Normality=\frac{\text {gram equivalents of solute}}{\text {Volume in L}}[/tex]

[tex]{\text {gram equivalents of solute}}=\frac{\text {given mass}}{\text {Equivalent mass}}[/tex]

Thus [tex]Molarity=Normality\times \frac{\text {Equivalent mass}}{\text {Molar mass}}[/tex]
