$\text{M}=\text{molarity}$  of the solution, $\text{m}=\text{molality}$ of the solution

$\text{d}=\text{density}$ of the solution $\left(\text{in}\text{g}\text{.}{\text{mL}}^{-1}\right),{\text{M}}^1=\text{gram}$ molecular weight of solute

Which of the following relations is correct

$\text{Total}\text{weight}\text{of}\text{solution}=1000+\text{nM}$

$\text{Volume}\text{of}\text{solution}=\frac{1000+{\text{nM}}^1}{\text{d}}$

$\text{Molarity}\left(\text{M}\right)=\frac{\text{n}}{{\text{V}}_{\left(\text{ml}\right)}}\times 1000$

$=\frac{\text{n}}{\frac{100+{\text{nM}}^1}{d}}\times 1000$

$\text{M}=\frac{\text{nd}\times 1000}{1000+{\text{nM}}^1}$

$1000\times \text{M}+{\text{nMM}}^1=\text{nd}\times 1000$

$\text{n}=\frac{1000\text{M}}{1000\text{d}-{\text{MM}}^1}$

$\text{m}=\frac{\text{n}}{\text{kg}}=\frac{1000\times \text{M}}{\left(1000\text{d}-{\text{MM}}^1\right)}$
