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?

Answer:

The reaction of 45 g of glucose will produce 66 g of #CO_2#

Explanation:

Here is the balanced equation:

#C_6H_12O_6 + 6O_2 rarr 6 CO_2 + 6 H_2O#

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

#"no. of moles" = (45g)/(180g) = 0.25# mole

The equation tells us there are 6 moles of #CO_2# produced for each 1 mole of glucose that reacts. There fore, we will obtain

#6xx0.25 = 1.50 "moles of " C_6H_12O_6#

Finally, converting to mass

#1.50 "moles" xx 44 g/"mole" =66 g#
