How many grams of CO2 (Mm = 44.0 g/mol) are produced in the combustion of 31.0 g of C4H10 (Mm = 58.1 g/mol)?

Answer 1

C4H10 + 9mO2 ==> 4CO2 + 10H2O

mols C4H10 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols C4H10 to mols CO2
Now convert mols CO2 to g CO2 by grams CO2 = mols CO2 x molar mass CO2
