Question

1. If 2.8 moles of propane reacts with excess oxygen. How many grams of CO2 will form?

Answer 1

from the balance chemical equation we have the mole ratio of propane and the produced CO₂ as 1:3. having the moles of propane that reacted as 2.8 will react with 8.8 moles of CO₂.

mass=molar mass* number of moles

mass=44g*8.4moles=369.6g
