What is the density of a sample of rubbing alcohol if it has a specific gravity of 0.789?

Specific gravity  is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as. SG = ρsubstance / ρH2O . We calculate as follows:

0.789 = ρsubstance / 1000 kg/m^3
ρsubstance = 789 kg / m^3

Hope this answers the question. Have a nice day.

Usually this mountain-building process produces majestic peaks and steep slopes. you should look for these along the other features.
