## How many moles is 4.00 grams of O2?

Unlock

Since oxygen has an atomic mass of 16 g/mole, the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole. Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## How many moles is 4g of he?

1) The molar mass that is the mass of 6.022 X 10 23 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023 atoms of He.
