how many moles of CO2 are produced from 2.90 moles of C3H8? C3H8 + 5O2 yields 3CO2 +4H2O
Let's see. 1 mole C3H8 produces 3 moles CO2. So 2 moles C3H8 must produce 6 moles CO2. And 3 moles C3H8 must produce 9 moles CO2. Hmmm. What will 2.90 moles C3H8 produce?
To determine how many moles of CO2 are produced from 2.90 moles of C3H8, we need to use the balanced chemical equation provided: C3H8 + 5O2 yields 3CO2 + 4H2O.
In the balanced equation, we can see that one mole of C3H8 reacts to produce three moles of CO2. Therefore, we can set up a proportion:
(2.90 moles C3H8) / (1 mole C3H8) = (x moles CO2) / (3 moles CO2)
Cross multiplying, we get:
2.90 moles C3H8 * 3 moles CO2 = 1 mole C3H8 * x moles CO2
8.70 moles CO2 = x moles CO2
So, 2.90 moles of C3H8 produce 8.70 moles of CO2.
