A tanker with a volume of 50 cubic meters is filled with oil. 30ml of oil is sampled from the oil tank and its mass is 24.6 g. then the tanker can hold () t of oil

A tanker with a volume of 50 cubic meters is filled with oil. 30ml of oil is sampled from the oil tank and its mass is 24.6 g. then the tanker can hold () t of oil


It can be seen from the question that 24.6x10 ^ (- 3) kg oil is 0.03l, so the oil density can be calculated as 24.6x10 ^ (- 3) △ 0.03 = 0.82kg/l
And 1 cubic meter = 1 000 liters
Therefore, the oil vehicle can hold 0.82kg/lx1000x50 = 41000kg = 41t of oil



A tanker carries 30m3 of oil. Take 30ml of oil out of the tanker and weigh it to be 24.6g. What is the total mass of oil in the tanker?


According to the formula ρ = MV, the density of oil is ρ = m1v1 = 24.6g30cm3 = 0.82g/cm3 = 0.82 × 103kg / m3, and the total mass of oil is m = ρ v = 0.82 × 103kg / m3 × 30m3 = 2.46 × 104kg
