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 :

Answer

A, B

Explanation

`underset(34 xx 24 g)underset(342 g)(C_(12)H_(22)O_(11)) + underset(?)underset(12 xx 32 g)(12O_(2)) to 12 CO_(2) + 11 H_(2)O`
Energy requirements in a day = `34 xx 24`g of sucrose
Amount of oxygen needed for burning 342 g of sucrose `=12 xx 32`g
Amount of oxygen needed for burning `=34 xx 24`g oof sucrose
`(12 xx 32)/342 xx 34 xx 24`
=916.2 g
