## Density Assumptions

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Density Assumptions

When given water in a problem where we use its density, can we always assume it is pure water and that its density is 1 g/mL?

Yes, the equation sheet gives the density of water is 1g/mol.
