Atoms and Atomic Structure
If the atomic weight of oxygen is sixteen what would be the atomic weight of calcium?
As per the modified periodic table, the fourth element after
oxygen considering their atomic weights is Ca and thus if the
atomic weight of oxygen is considered to be as 16, therefore the
atomic weight of Ca is 20

How many grams of oxygen gas are required to produce 100g of calcium oxide?
The chemical formula for Calcium Oxide is CaO. The Atomic weigth of Calcium is 40.078. The Atomic weight of Oxygen is 15.999 The Molecular weight of CaO is therefore 56.077 Thus 100g of CaO would contain (15.999/56.077)*100 = 28.53041353852738 grams of Oxygen and (40.078/56.077)*100 = 71.46958646147262 grams of Calcium.
