Question

Propane (CH3CH2CH3) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). How many moles of propane would be needed to produce 0.60 moles of carbon dioxide?

Answer 1

Answer:

0.20 moles of propane would be needed to produce 0.60 moles of carbon dioxide.

Explanation:

Molecular formula of propane is $C_{3}H_{8}$

Balanced chemical reaction:

$C_{3}H_{8}+5O_{2}\rightarrow 3CO_{2}+4H_{2}O$

According to balanced reaction-

3 moles of $CO_{2}$ are produced from 1 mol of propane

Hence, 0.60 moles of $CO_{2}$  are produced from $\frac{1\times 0.60}{3}$ moles of propane or 0.20 moles of propane

Therefore, 0.20 moles of propane would be needed to produce 0.60 moles of carbon dioxide.
