The mass of the tanker with petrol is 250000 N.
We are given that,
Mass of tanker= m =2800 kg
Volume of petrol= v =30 m³
Density of petrol= d =740 kg/m³
Thus , mass , density and volume relation can be given as,
density= mass/ Volume
Mass = Density × Volume
Mass = 740× 30
Mass = 22200 kg
The mass of the petrol is 22200 kg.
Total mass of tanker with petrol = Mass of petrol + Mass of tanker
Total mass of tanker with petrol= 22200+ 2800 kg
Total mass of tanker with petrol= 25000 kg
Total weight of the tanker with petrol = Mass of tanker full of petrol× g
Where, weight = m × g ,(g =10m/s²)
Total weight of the tanker with petrol= 25000×10 = 250000 N
Therefore, the mass of petrol, total mass of tanker with petrol and weight of tanker with petrol would be 22200 kg, 25000 kg and 250000 N.
