how would i work out the problem for: a sample of oil has a mass of 65g and a volume of 80.0 ml what is its specific gravity. please show formula. thank you.

To calculate the specific gravity of a substance, you need to know the mass of the substance and the volume of the substance. The specific gravity is the ratio of the density of the substance to the density of water at a particular temperature. The formula to calculate specific gravity is:
Specific Gravity = (Density of Substance) / (Density of Water)
To calculate the density of the oil, you need to divide the mass of the oil by its volume:
Density of Oil = Mass of Oil / Volume of Oil
In this case, you are given that the mass of the oil is 65g and the volume is 80.0 ml:
Density of Oil = 65g / 80.0 ml
Now, keep in mind that water has a density of 1 g/ml (at 4 degrees Celsius), so to find the specific gravity, you need to divide the density of the oil by the density of water:
Specific Gravity = (65g / 80.0 ml) / (1g / 1 ml)
Simplifying the equation:
Specific Gravity = (65g) / (80.0ml) * (1ml / 1g)
Specific Gravity = 0.8125
So, the specific gravity of the oil in this case is 0.8125.
