## 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 do you find moles from liters and molarity?

Calculating Moles Given Molarity

To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.

## How do you convert 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, 6.02×1023. 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.

## How do you convert liters to moles?

At standard temperature and pressure [STP], 1 mole of ideal gas is equal to 22.4 liters. Thus, the conversion ratio used in the formula below is 22.4. Thus, the amount of substance in moles is equal to the volume of ideal gas in liters divided by the conversion ratio of 22.4 L/mol.
