Final answer:
The mass of one litre of oil of density 926 kg/m³ is 0.926 kg.
Step-by-step explanation:
The mass of one litre of oil can be calculated using the formula:
Mass = Density x Volume
Given that the density of the oil is 926 kg/m³ and the volume is 1 litre (which is equivalent to 0.001 m³), we can substitute these values into the formula to calculate the mass:
Mass = 926 kg/m³ x 0.001 m³ = 0.926 kg
Therefore, the mass of one litre of oil is 0.926 kg.
