What mass of CO2 could be formed from the reaction of 16 g of CH4 with 32 g of O2 ?

• Chemistry -

Here is a worked example of a stoichiometry problem. http://www.jiskha.com/science/chemistry/stoichiometry.html

• Chemistry -

C H4 + 2 O2 --> CO2 + 2H2O
C is 12 g/mol
CH4 is 16 g/mol so we have one mol

O is 16 g/mol
O2 is 32 g/mol
so we have one mole but we need 2
so
Only half a mole of CH4 reacts with the one mole of O2
That is 6 grams of C with 16 of our 32 grams of O
so 6 + 16 = 22 grams of CO2
