    Mar 19, 2012 · The correct answer is “e”. The mass of one atom of copper is going to be extremely small, so only letter “e” makes sense. The calculated solution is (1 Cu atom) × (1 mol Cu/6.02×10 23 Cu atoms) × (63.55 g Cu/1 mol Cu). 6.022×10 23 Cu atoms; 63.55 g of Cu is 1 mole of Cu, which is equal to Avogadro’s number. It can be calculated by adding the invididual molar mass of every atom that are composing the molecule (CH4 : 1 atom of C -> molar mass = 12.011 g/mol + 4 atom of H -> molar mass = 1.008 g/mol -> molar mass of CH4 = 12.011+4*1.008=16.043 g/mol)
