Question

Determine the volume of a 75-gram sample of gold at stp

Answer 1

Let V = the volume of the sample at STP.

The mass is  m = 75 g
The density of gold is 19.32 g/cm³

Because density = mass/volume, therefore
(19.32 g/cm³) = (75 g)/(V cm³)
V = (75 g)/(19.32 g/cm³) = 3.882 cm³

Answer: 3.882 cm³
