• Starting with the same 50.0g of CH 4 , how<br />
many liters of CO 2 gas at STP will be<br />
produced?<br />
• The problem starts out just the same as<br />
before: Convert g known to moles.<br />
• 50.0g CH 4 x (1 mol/16.0g) = 3.12 mol CH 4<br />
• Next, use the mole ratio from the equation to<br />
convert mols known to mols unknown.<br />
• 3.12 mol CH 4 x (1 mol CO 2 /1 mol CH 4 ) = 3.12<br />
mol CO 2
