How many moles of carbon dioxide would be produced if 0.28 moles of propane, C3H8, were combusted? C3H8 + 5 O2 --> 3 CO2 + 4 H20

Answer 1

C3H8 + 5 O2 --> 3 CO2 + 4 H20

This shows that for every mole of propane combusted, three moles of carbon dioxide are produced.

Now, we have 0.28 moles of propane.

1 mol of C3H8 -> 3 mol of CO2
0.28 * 1 mol of C3H8 -> 0.28 * 3 mol of CO2
0.28 mol of C3H8 -> 0.84 mol of CO2
