What is the specific gravity of an object.....?

Question

What is the specific gravity of an object that weighs 13.35 g and has a volume of 25.00 mL? The density of water under the same conditions is 0.980 g/mL. ?

Answer 1

sp gravity is the density related to H2O with a density of 1.000g/mL.

density of object = 13.35 g / 25.00mL = x to 4 significant digits

sp grav of H2O = 1.000 = 0.980 g/mL/0.980 g/mL

sp grav of object = x g/mL / 0.980 g/mL = y to 3 significant digits
