The density of a sample of rubbing alcohol if it has a specific gravity of 0.789 the density of water is 1.000 g/ml will be 789 kg/m3.
Specific gravity was the proportion of a substance's density (mass per unit volume) to particular reference material, frequently a liquid. Specific gravity equals a substance's density (g/mL). Water density (g/mL) for the same temperature
Specific gravity can be calculated as:
Specific gravity = density of substance / density of water
0.789 = density of substance / 1000 kg/m3
density of substance = 0.789 × 1000 kg/m3
density of substance = 789 kg/m3.
Therefore, the density of a sample of rubbing alcohol if it has a specific gravity of 0.789 the density of water is 1.000 g/ml will be 789 kg/m3.
