$D = \frac{n \times M M}{V}$ $D=(nxxMM)/V$

Explanation:

The density $D$ $D$ is calculated by: $D = \frac{m}{V}$ $D=m/V$ .

The relationship between the mass $m$ $m$ and the molecular weight $M M$ $MM$ is the following: $n = \frac{m}{M M} \Rightarrow m = n \times M M$ $n=m/(MM)=>m=nxxMM$ , where, $n$ $n$ is the number of mole of the substance in question.

Therefore, $D = \frac{n \times M M}{V}$ $D=(nxxMM)/V$ .
