sample porblems of specific gravity with solution?

Answer 1

A specific gravity is a ratio of density of a liquid to the density of water. That given

Problem #1. What is a specific gravity of a fluid that weighs 4.575kg and occupiers a volume of 4607 ml.
density p=mass (m)/ volume (v)

p=m/v=4575g /4607cm^3 = 0.9930 g/cm^3

p(H2O)=1g/cm^3

Specific gravity SG=p/p(H2O)=0.9930

Problem #2 lets solve the same problem bu a a temperature of 20 deg C or 68 F p(H2O)= 0.9982071 g/cm^3

SG=0.9930 /0.9982071 = 0.9947 (slightly different answer than #1)

Note liquids can be identified by known SG
Also amount of one liquid diluted in another can be determined by measuring a SG of that mixture. For instance determination of amount of alcohol in a drink.
Does that help?
