Question

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 1

Answer:
`Molarity=Normality* (gew)/(gmw)`

Step-by-step explanation:

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

`Molarity=\frac{\text {moles of solute}}{\text {Volume in L}}`

`{\text {moles of solute}=\frac{\text {given mass}}{\text {Molar mass}}`

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

`Normality=\frac{\text {gram equivalents of solute}}{\text {Volume in L}}`

`{\text {gram equivalents of solute}}=\frac{\text {given mass}}{\text {Equivalent mass}}`

Thus
`Molarity=Normality* \frac{\text {Equivalent mass}}{\text {Molar mass}}`
