From this we can calculate the number of carbon-12 atoms in 12 grams of carbon-12: 12 g X 1 carbon-12 atom = 6.021 X 1023 carbon-12 atoms 1 1.993 X 10–23 g (from Clugston and Flemming, Advanced Chemistry) This is the basis of Avogadro’s number. Better experimental methods have yielded the more accurate value of Avogadro’s number we have today. The RAM of O is 16g. The number of moles of O in the 3.2g is 3.2/16 = 0.2. Since the M and O gave the same number of moles in the MO, that is their mole ratio is 1:1, then the number of moles of the M in the MO is also 0.2. Therefore, if 0.2 mole if M weighs 12.8g, then 1 mole of M will weigh 1*12.8/0.2 = 64g/mole. 1 mole/63.546 g. and the calculation would be: 14.886 X 1 mole/63.546 g = 0.250 moles. The number of atoms of Cu would be: 0.250 moles x 6.022 X 10 23 atoms/mole = 1.506 x 10 23 atoms. The conversion between grams and moles is the most frequent calculation that will be done in this class. Rarely will the number of atoms be calculated.
