## How many liters are in 2 moles of O2?

1mol O2 occupies 22.4L of volume at STP. so 2mol O2 occupies **44.8L** of volume at STP.

## How much volume does a mole of oxygen occupy?

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.

## What is P1 V1 P2 V2?

The relationship for Boyle’s Law can be expressed as follows: **P1V1 = P2V2**, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.

## How do you calculate moles to liters?

Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L. Converting from particles (atoms, molecules, or formula units) to moles: Divide your particle **value** by Avogadro’s number, 6.02×10^{23}. Remember to use parentheses on your calculator!

## What is the moles of oxygen?

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to one mole of oxygen is **15.998 grams** and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
