Methane, CH4\text{CH}_4CH4​, reacts with oxygen, O2\text{O}_2O2​, to form carbon dioxide, CO2\text{CO}_2CO2​, and water, H2O\text{H}_2\text{O}H2​O.

The balanced symbol equation is shown: CH4(g)+2O2(g)→CO2(g)+2H2O(l)\text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{l})CH4​(g)+2O2​(g)→CO2​(g)+2H2​O(l)

Calculate the mass of carbon dioxide made from 80.0 g80.0\text{ g}80.0 g of methane.

(The relative atomic mass, ArA_rAr​, of H\text{H}H is 1.01.01.0, of C\text{C}C is 12.012.012.0 and of O\text{O}O is 16.016.016.0).
