Chapter 9, Problem 61APP

Pentane gas ( $C_5{H}_{12}$ ) reacts with oxygen to produce carbon dioxide and water. (9.2. 9.3. 9.4)
$C_5{H}_{12}\left(g\right)+8O_2\left(g\right)\stackrel{\Delta }{\to }5C{O}_2\left(g\right)+6H_{2}O\left(g\right)$

a. How many moles of $C_5{H}_{12}$ must react to produce 4.00molof $H_{2}O$ ?
b. How many grams of $C{O}_2$ are produced from 32.0 g of $O_2$ ?
c. How many grams of $C{O}_2$ are formed if 44.5 g of $C_5{H}_{12}$ is mixed with 108 g of $O_2$ ?
