What is the density of a substance in kg/mL, if a sample with a volume of 117.52cm3 has a mass of 0.29956kg?
Density =Mass / Volume
D =0.29956 kg / 117.52 cm^3, 1 cm^3 = 1 mL
D =0.002549..... kg/mL. P.S. Your units should be consistent. That is, Kg should go with m^3, and g(grams) should go with cm^3. So that: 0.002549 x 1,000 =2.549 g/cm^3.
A mL is generally used for "liquid measure" and cm^3 for "dry measure".
