The correct relationship between molality (m) and molarity (M) of… - Vidyadip

MCQ

The correct relationship between molality $(m)$ and molarity $(M)$ of a solution is ($d =$ density in $g/ml$ )

A
$m = \frac{d}{M} - \frac{{1000}}{{{M_{\left( {solute} \right)}}}}$
B
$\frac{1}{m} = \frac{M}{d} - \frac{{1000}}{{{M_{\left( {solute} \right)}}}}$
✓
$\frac{1}{m} = \frac{d}{M} - \frac{{{M_{\left( {solute} \right)}}}}{{1000}}$
D
$\frac{1}{m} = \frac{d}{M} \times \frac{{{M_{\left( {solute} \right)}}}}{{1000}}$

✓

Answer

Correct option: C.

$\frac{1}{m} = \frac{d}{M} - \frac{{{M_{\left( {solute} \right)}}}}{{1000}}$
