The Specific Gravity of kerosene is 0.786. What is the volume occupied by 7.75kg of kerosene?
Is it 7.75/0.786?
neither.
mass = volume x density or
volume = mass/density.
density = specific gravity here.
To calculate the volume occupied by a substance, you can use the formula: volume = mass / density.
However, in this case, we are given the specific gravity of kerosene, not the density. Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water.
The specific gravity of kerosene is 0.786, which means that kerosene is 0.786 times as dense as water.
To calculate the volume occupied by 7.75 kg of kerosene, we need to convert the specific gravity into density.
The density of water is approximately 1000 kg/m^3. So, we can calculate the density of kerosene by multiplying the specific gravity by the density of water:
Density of kerosene = Specific gravity of kerosene * Density of water
Density of kerosene = 0.786 * 1000 kg/m^3
Density of kerosene = 786 kg/m^3
Now we can use the formula volume = mass / density to find the volume:
Volume = 7.75 kg / 786 kg/m^3
Volume = 0.009864 m^3
Therefore, the volume occupied by 7.75 kg of kerosene is approximately 0.009864 cubic meters.
