The hourly energy requirement of an astronaut can be satisfied by the energy relesed when 34 g of sucrose `(C_12H_22O_11)` are burnt in his body. How many g of oxygen would be needed to be carried in space capsule to meet his requirement for one day :

A

916.2 gm

B

91.62 gm

C

8.162 gm

D

9.162 gm

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(12)H_(22)O_(11) + 12O_(2) rarr 12CO_(2) + 11H_(2)O`, 1 mole of starch requires 12 moles of oxygen
`:. (34)/(342)` moles of starch requires `(34)/(342) xx 12 xx 32 xx 24 = 916.2 gm`
