Answer 1

Hello, Julia,

I didn't see this until this morning, so sorry I'm late.

First, balance the reaction and then calculate the number of moles of methane. balanced equation says we'll get one mole CO2 for every 1 mole CH4. Since we burned 3.63E-04 moles methane, that's the same number of moles we'll get for CO2. Convert that back to grams.

3.63E-04 moles CO2 is 1.60E-02 grams CO2
