in the process of repiration in plants 180 gms of sugar plus 192 gms of oxygen produce

Options

A. Large amount of `CO_(2)` , no water and no energy
B. 132 gms of `CO_(2)` , 534 gms of water and 337 kcalas of energy
C. 264 gms of `CO_(2)`,180 gms fo water and 674 kcals of energy
D. 528 gms of `CO_(2) , 216 gms of water and 1348 kcals of energy

Answer

C

Explanation

Reaction of respiration is
`C_(6)H_(12)O_(6)+6O_(2)rarr6CO_(2)+6H_(2)O+674`kcal
In this reaction considering molecular weight of each elements, we get
`C_(6)H_(12)O_(6)=6` time 12+12 time 1+6 times 16=180gm
`O_(2)=6` times 32=192gm
Now we consider products of this reaction i.e. `6CO_(2)` and `6H_(2)O`
`6CO_(2)=6(12+32)=264gm`
`6H_(2)O=6(2+16)=108gm`
