# When propane C_3H_8 reacts with oxygen, carbon dioxide and water are produced. If 7.51 grams of propane react with excess oxygen, how many grams of carbon dioxide are formed?

Mar 10, 2016

${C}_{3} {H}_{8} \left(g\right) + 5 {O}_{2} \left(g\right) \rightarrow 3 C {O}_{2} \left(g\right) + 4 {H}_{2} O \left(g\right)$

Approx. $22 \cdot g$ carbon dioxide will result.

#### Explanation:

From the equation above, 3 moles of carbon dioxide result from every mole of propane combusted.

We had, $\frac{7.51 \cdot g}{44.1 \cdot g \cdot m o {l}^{-} 1}$ $=$ ?? "moles of propane".

So how many moles of carbon dioxide? And what is the mass of this quantity?
