Question

How many grams of CO2 is produce by burning 2.50 mole of CH4 in an excess of O2

Answer 1

Explanation:

Whenever you find such questions……Just write the chemical equation that we are going to form out of it. So that is going to be :

CH4 +2 O2 — CO2 +2 H2O

Now we see that for 1 mol i.e. 16 grams of methane results in 1 mol of CO2 or 44 grams of CO2.

That means for 2.50 moles or 40=(16×2.50) grams of methane (CH4). We will obtain (44×2.50)= 110 grams of CO2 .That's it….
