How many grams of carbon dioxide gas are formed when 11.9g of liquid hexane (C6H14) is combusted?

1 answer

2C6H14 + 19O2 ==> 12CO2 + 14H2O

mols hexane = grams/molar mass = ?

Using the coefficients in the balanced equation, convert mols Hexane to mols CO2. You can see that 2 mols hexne will produce 12 molsl CO2.

Convert mols CO2 to grams. grams = mols x molar mass
