Question

What mass of carbon dioxide (CO2) is produced when 62.8g of methane (CH4) reacts with oxygen (O2)?

Answer 1

Step-by-step explanation:

Hello!

In this case, when methane is burnt in the presence of carbon dioxide, the following chemical reaction is carried out:

`CH_4+2O_2\rightarrow CO_2+2H_2O`

Thus, since there is a 1:2 mole ratio between methane and oxygen, we set up the following mathematical expression to obtain the produced mass of carbon dioxide as a result of the reaction:

`m_(CO_2)=62.8gCH_4*(1molCH_4)/(16.05gCH_4)*(1molCO_2)/(1molCH_4) *(44.01gCO_2)/(1molCO_2) \\\\m_(CO_2)=172.2gCO_2`

Best regards!
