well, the moles will be proportional to pressure. Balance the equations: CH4+2O2>>CO2 + 2H20 **1 C2H6+7.5 O2>> 2CO2 + 3H2O **2 so in methane, one gets the same amount of CO2 as CH4 In the ethane, one gets twice as much. So,of the final pressure, the difference is ...

First balance C's, then H's, then O's using coefficients so you have equal numbers of each element on the sides of the equation. So first you would match up the C's C2H5OH + O2 -> 2CO2 + H2O then do the H's (six on left so need 6 on right) C2H5OH + O2 -> 2CO2 + 3H2O then...

2CO + O2 ==> 2CO2 Convert 10.0 g CO to moles. moles = grams/molar mass Convert moles CO to moles CO2 using the coefficients in the balanced equation. That is a 1:1 ratio. Convert moles CO2 to grams. Grams = moles x molar mass.
