Answer the following question by referring to the reaction stoichiometry given

C3H8 +5 O2 > 3 CO2 + 4 H2O


a) Calculate the mass of H2O is produced from the reaction of 6.3g of propane
b) Calculate how many molecules of H2O are produced when 2 moles of O2 are reacted with an excess of propane
c) Calculate how many atoms of hydrogen in water are produced when 2.4 moles of propane are reacted
d) Calculate how many molecules of CO2 are produced when 2.3 x10 6 atoms of O2 are reacted
e) CALCULATE THE MASS OF CO2 produced when 6.5 g of propane is reacted with 14.2 g of O2

the average human being contains 60 trillion living cells. if there are currently 7.217 million people on earth. how many moles of living human cells are currently on our planet? if 150billion humans have inhabited the planet in all of history, how many moles of human cells have existed so far on our planet?
