    Ok so first you have to find the molar mass of 1 mole of neon. This is on the periodic table as 20.18g. If it is asking for a sample of 68.4g of neon you need to set the equation up as 68.4g x (1 mol/20.18g). So you would then multiply the two masses and end up with a final answer of 1380.312 moles. Do you understand?
