Answer:

1 mol of methane is 16 grams that produces 6.25 moles of #CO_2# when it is burnt

Explanation:

1 mol of methane is 16 grams. Therefore, if you have 100 grams of methane, it means that you have #100/16=6.25# moles of methane.

When you burn 6.25 moles of methane, you produce 6.25 moles of carbondioxide.

Your reaction is wrong though. I want to correct it.

#CH_4 + 2O_2 -> CO_2 + 2H_2O#

When you burn 6.25 moles of methane, you need 12.5 moles of oxygen gas.

When you burn 6.25 moles of methane, you produce 6.25 moles of carbondioxide (275 grams of #CO_2#) and 12.5 moles of water vapour (225 grams of #H_2O#).
