Standard Temperature and Pressure Video Lessons

Concept: Standard Temperature and Pressure

# Problem: Use the molar volume of a gas at STP to calculate the density (in g/L) of carbon dioxide gas at STP.

###### FREE Expert Solution

Recall that standard temperature and pressure (STP) is defined as 1 atm and 0 ˚C.

• Recall: 1 mol of an ideal gas occupies a volume of 22.4 L at STP

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

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

molar mass of CO2 = 44.01 g/mol

The density of CO2 gas is:
