Mathematics of Chemical Reactions
Example #1:How many moles of hydrogen are required to react exactly with 4.13 mol of oxygen?
2 H2(g) + O2(g) 2 H2O(g)
? mol 4.13 mol
Example #2:Determine the number of moles of natural gas (methane) that must undergo combustion to produce 1.62 mol of water vapor.
CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g)
? mol 1.62 mol
