What mass of carbon dioxide isproduced from the complete combustion of 6.20×103g

Question

What mass of carbon dioxide isproduced from the complete combustion of 6.20×103grams of methane?
when methane (CH4) burns, itreacts with oxygen gas to produce carbon dioxide and water. Theunbalanced equation for this reaction is CH4 + O2 --> CO2 + H2O What mass of carbon dioxide isproduced from the complete combustion of 6.20×103grams of methane?
when methane (CH4) burns, itreacts with oxygen gas to produce carbon dioxide and water. Theunbalanced equation for this reaction is CH4 + O2 --> CO2 + H2O

Explanation / Answer

CH4 + 2 O2 --> CO2 + 2 H2O
so....
1 mole of methan yielts o mole of CO2
so...6.2e-3g CH4=0.000386467mol CH4 = moles of CO3
so...
0.000386467mol CO2=0.0170083g CO2
