Answer:
1504g of oxygen was consumed
Explanation:
C31H64 + 4702 —> 31C02+ 32H20
From the equation, we see clearly that 47moles of O2 was consumed in the reaction.
Molar Mass of O2 = 32g/mol
Number of mole of O2 = 47moles
Mass conc. Of O2 = number of mole x molar Mass
Mass conc. Of O2 = 47 x 32 = 1504g
Therefore, the mass of oxygen consumed in the reaction is 1504g.
