Question

When glucose is consumed by humans, 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 grams of glucose $C_6 H_{12} O_6$ completely react with oxygen?a. 1.5 gb. 1.8 gc. 11 gd. 66 g

Answer 1

The reaction of 45 g of glucose will produce 66 g of CO2

Explanation:

Here is the balanced equation:

C6H12O6+6O2→6CO2+6H2O

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

no. of moles = 45g divided by 180g=0.25 mole

The equation tells us there are 6 moles of CO2 produced for each 1 mole of glucose that reacts. There fore, we will obtain

6×0.25=1.50moles of C6H12O6

Finally, converting to mass

1.50moles×44g mole

=66g
