2C(s) + 2H2O(l) ==> CH4(g) + CO2(g)
A. What mass of carbon is needed to produce 16.04 L of methane at STP?
B.What volume of carbon dioxide at STP is produced from 829 g of carbon?
Ok, I need help, I have tried these problems and I think I have the correct answer.
A.17.2 g
B.773 L
PLEASE HELP!

A hint to get you started...
Assume that CO2 behaves as an ideal gas, in that 1 mole of it will be assumed to occupy 22.4L at STP. You can then figure out how many moles of CO2 you have. Relate that to the moles of C and then convert that to mass.

Your answers are correct! Good job! The key was knowing 22.4L gas at STP and using mol-mol ratios.
