Question on: JAMB Physics - 1997
An empty 60 litre petrol tank has a mass of 10kg. Its mass when full of fuel of relative density 0.72 is
A
7.2kg
B
33.2kg
C
43.2kg
D
53.2kg
Ask EduPadi AI for a detailed answer
Correct Option: C
R.d = \(\frac{\text {density of petrol}}{\text{density of water}}\)
0.72 = \(\frac{\text{density of petrol}}{1000}\)
Density of petrol =720kgm3
mass of petrol = 720 x 60 x 10-3
=43.2kg
0.72 = \(\frac{\text{density of petrol}}{1000}\)
Density of petrol =720kgm3
mass of petrol = 720 x 60 x 10-3
=43.2kg
