Answer to Question #237926 in General Chemistry for Kenzie

Question

If a Boeing 767 aircraft, requires 49163 lb of fuel to make the trip from Toronto to Edmonton, and already has 8000 L of fuel in the tank, how many litres of fuel need to be added to ensure sufficient fuel? The density of the fuel is 0.8 kg / L

Answer 1

mass of fuel already on board

= 8000litres × 0.8 kg/L

=6400 kg

mass of fuel required

if 49,200 lb = 22,300 kilograms

49163 lb= ?

(49163 lb /49,200lb)22,300 kilograms

=22288 kilograms

mass of additional fuel required

=(22288-6400)

=15888 kilograms

 volume of additional fuel required

15888 kg /0.8 kg/L

=19860litres
