HCCS Stoichiometry Post Activity Moles of Carbon Dioxide Gas Question

I’m working on a chemistry question and need support to help me learn.

Consider the following reaction:

C3H8 (g) + 5O2 (g) ⟶ 3CO2 (g)+ 4H2O (l)

How many moles of carbon dioxide gas will be produced by the rapid combustion of 180 g of propane (C3H8) according to the reaction?

Group of answer choices

1.4 mol

12.3 mol

4.1 mol

5.9 mol

Consider the following reaction:

C3H8 (g) + 5O2 (g) ⟶ 3CO2 (g)+ 4H2O (l)

2. If every mole of carbon dioxide (assuming STP) yields 22.4L, how many liters of gas are formed by the rapid combustion of 180 g of propane (C3H8) according to the reaction?

31 L
92 L
276 L
132 L
