Question

What is the mass of glucose required to produce 44g of Co2 on complete combustion

Answer 1

Mass of glucose is 180g
Mass of CO2 formed in reaction is 44 x 6 is equal to264g
So glucose required is 180 x 44 divided by 264 gives 30 g
Answer is 30g

Answer 2

HI

C6H12O6 + 6 O2 --->6 H2O +6 CO2

Hence 180g of glucose is needed to produce 264g of co2 
So, for producing 44g of CO2, 180 x 64 / 264g of glucose needed = 180/6= 30g.

hence 30g of glocose required to produce 44g of CO2 on complete combution.
