Question

The volume of a molecule can be calculated by the substrates density and molar mass. Show how this can be done.

Someone, who can help with this?

Answer 1

You know the formula,
\[\text{density}=\frac{\text{Mass}}{\text{Volume}}\]
And,
\[\text{Mass=moles}\times\text{Molar Mass}\]So,
\[V=\frac{M}{d}=\frac{n\cdot Mm}{d}\]
Where, d is density, Mm, molar mass and n is the mole number.

Answer 2

like John described, the density depends on volume and mass. since mass is given with the mol information, and you also know the density, the remaining divisor "volume" can be determined.
