CH4 + 2O2 ==> CO2 + 2H2O
Convert 8.0 g CH4 to moles. moles = grams/molar mass.
8.0/16 = 0.5 mole CH4.
Now look at the equation. The equation tells us that 1 mole CO2 is formed for 1 mole CH4; therefore, 0.5 mole CO2 will be formed by 0.5 mole CH4.
Methane, CH4 burns in oxygen gas to form carbon dioxide and water. How many moles of carbon dioxide will be formed from 8.0g of methane?

Hey so not too hard.
1. write the balanced equation: CH4+2O2->CO2+2H2O
2. convert 8.g of CH4 to moles (n=m/M): 8.0/16=0.5 mole CH4
3. refer to the above equation- it states that 1 mole CO2 is formed for 1 mole CH4 (giving the ratio 1:1) and therefore, means 0.5 mole CO2 will be formed by 0.5 mole CH4
