Full Answer

To determine the density of a liquid, such as phosphoric acid, divide the liquid's mass by its volume. If the pressure increases while the temperature remains the same, then the density also increases. Likewise, if the pressure decreases while the temperature is constant, then the density of the liquid also decreases.

Phosphoric acid is a common chemical used to create household cleaning products.
