How many moles are in 2g of oxygen?
We know that 2g of O2 has 0.0625 moles of O2. That means that the number of O2 molecules present in 2g of O2 is equal to 0.0625*NA.
How many grams are in a mole?
The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol.
How did you convert moles to grams?
The amount of grams in a mole depends on the substance you have. To work it out, find the atomic or molecular mass of your substance and multiply it by the number of moles you have. For one mole, the atomic or molecular mass will be the same as the weight.
