Answer:
The answer is c
Explanation:
this is so as when we multiply 6 with the whole equation it forms glucose and glucose + oxygen is the basic respiration equation which is balanced in the following way:
C6H12O6 +6O2----> 6CO2 + 6H20
by observing this equation we can se that there are 6 moles of oxygen present thus we will multiply the 6 with 24 by using the formula:
moles= volume(dm3)/24
6=vol/24
6*24=volume
volume of oxygen= 144
