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