Question

A. How many mole of CO2 can be produced when 2.25 moles of C3H8 reacts?

B. Calculate how many moles of oxygen must react with propane to produce .756 moles of water. Balance the equation first:

C3H8(g)+O2(g)—>CO2(g)+H2O(g)

Answer 1

 

C3H8(g) + 5O2(g) ===> 3CO2(g) + 4H2O(g) ... balanced equation
A. 1 mole C3H8 produces 3 moles CO2. From that, you should be able to find out how many moles of CO2 are produced from 2.25 moles C3H8.
B. It takes 5 moles of O2 to react to make 4 moles water. From that, you should be able to figure out how many moles of oxygen it takes to make 0.756 moles H2O.
