We’re being asked to calculate the density (in g/L) of O2 gas at standard temperature and pressure.

Recall that density is the ratio of the mass and volume of an object:

$\overline{){\mathbf{density}}{\mathbf{=}}\frac{\mathbf{mass}}{\mathbf{volume}}}$

Also, recall that standard temperature and pressure (STP) is defined as 1 atm and 0 ˚C

We can use the ideal gas law to determine the volume occupied by 1 mole of any gas at STP: ###### Problem Details

Use the molar volume of a gas at STP to calculate the density (in g/L) of oxygen gas at STP.
