## Homework Statement

Calculate the total number of atoms in 2g of oxygen gas

## Homework Equations

molar mass

no of mole

## The Attempt at a Solution

I try to solve that by following steps but i don't know correct or not. in fact, i am so confused with mole

no of mole: 2 / 16x2 mol =0.0625mol

Number of oxygen: 0.0625 x 6.02x10^23 =7.525x10^22 atoms

is that correct?

but i am still confused with molar mass or no of mole,even number of atoms
