# When glucose is consumed, it reacts with oxygen in the body to produce carbon dioxide, water, and energy. How many grams of carbon dioxide would be produced if 45 g of C_6H_12O_6 completely reacted with oxygen?

The reaction of 45 g of glucose will produce 66 g of $C {O}_{2}$

#### Explanation:

Here is the balanced equation:

${C}_{6} {H}_{12} {O}_{6} + 6 {O}_{2} \rightarrow 6 C {O}_{2} + 6 {H}_{2} O$

Since the molar mass of glucose is 180 g, the 45 g given mass in this problem is

$\text{no. of moles} = \frac{45 g}{180 g} = 0.25$ mole

The equation tells us there are 6 moles of $C {O}_{2}$ produced for each 1 mole of glucose that reacts. There fore, we will obtain

$6 \times 0.25 = 1.50 \text{moles of } {C}_{6} {H}_{12} {O}_{6}$

Finally, converting to mass

$1.50 \text{moles" xx 44 g/"mole} = 66 g$
