## What volume will 2.00 moles of oxygen gas occupy at STP?

so 2mol O2 occupies **44.8L** of volume at STP.

## How do you find molar volume at STP?

At standard Temperature and Pressure (STP) the molar volume (V_{m}) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by **dividing the molar mass (M) by mass density (ρ)**. Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.

## How do you find volume at STP?

It can be written as: **V = nRT/P**. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”. R = 8.314472 J/mole x K.

## What is the volume of oxygen gas at STP?

Finally, use the fact that one mole of oxygen would occupy a volume of 22.4 L at STP to figure out the volume of the oxygen in this question at STP. The answer is **0.338 L (338 mL)**, but you will have to show the calculations to receive credit on your lab report.
