Answer:
Separated Oxygen (O):
Atomic mass of oxygen is 16.00.
Therefore molar mass of oxygen is also 16.00 g/mol.
Thus the mol is 40/16 = 2.5 mol
CO2 would also need that amount of moles, and CO2’s atomic and therefore
molar mass is 44.01.
Therefore mass of CO2 will be 44.01 * 2.5 = 110.025 g
Oxygen Gas (O2):
Atomic mass of oxygen is 16.00.
Therefore molecular mass of oxygen gas is 32.00.
Therefore molar mass of oxygen is also 32.00 g/mol.
Thus the mol is 40/32 = 1.25 mol
CO2 would also need that amount of moles, and CO2’s atomic and therefore molar mass is 44.01.
Therefore mass of CO2 will be 44.01 * 1.25 = 55.0125g.
