Suppose you're attempting to measure the density of the liquid that is highly volatile(it evaporates quickly). if you first measure the mass and then several minutes later measure the volume of the liquid will the measured density be higher then the true value, lower than the true value, or the true density of the liquid.

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
