{'cottonseed oil': [0, 0, 1, 0], 'litre': [2, 1, 1, 4], 'mass': [0, 0, 2, 3], 'density': [2, 0, 1, 3], 'm3': [1, 2, 2, 1], 'kg': [0, 1, 9, 24]}
The correct answer is option 3: 0.926 kg.
To understand why this is the correct answer, we need to use the formula for mass, which is density multiplied by volume. In this case, the density of cottonseed oil is given as 926 kg/m3.
We are asked to find the mass of one liter of cottonseed oil, which corresponds to one cubic meter. Therefore, we can directly use the given density value of 926 kg/m3 to find the mass.
Using the formula, mass = density x volume, we have:
mass = 926 kg/m3 x 1 m3
Since 1 liter is equal to 0.001 cubic meters, we can also express the volume as:
mass = 926 kg/m3 x 0.001 m3
By simplifying the equation, we find that the mass of one liter of cottonseed oil is 0.926 kg.
