An hourly energy requirement of an astronaut can be satisfied by the energy released when 34 grams of sucrose (C_(12)H_(22)O_(11))are burnt in his body. How many grams of oxygen would he need to be carried in space capsule to meet his requirement for one day ? |

Answer» SOLUTION :The astronaut consumes 34 g of sucrose in one hour. `therefore` Themassof sucroseneededinoneday `= 34 XX 24 = 816 g` The burning of sucrose in presence of oxygen is in accordance to the following equation. `UNDERSET(342.3 g)(C_(12)H_(22)O_(11)) + underset(384.0 g)(12 O_(2)) to 12 CO_(2) + 11H_(2)O` `therefore 342.3 g` of sucrose require for combustion, oxygen = 384.0 g `therefore 816 g` of sucrose will require for combustion, `=(384.0)/(342.3) xx 816 = 915.4 g` Hence, the astronaut should carry 915.4 g of oxygen in space capsule to meet his requirement for one DAY. |
