density is the ratio of mass to volume. mercury has a density of 1.36x10^4 kg/m^3. what is the density of mercury in units of g/cm^3

Answer:

1 kg = 1000 grams
1 m = 100 cm
So 1 m^3 = 1m x 1m x1m = 100 x100 x100 cm^3
so 1 kg /m^3 = 1000 grams / 10^6 cm ^3 = 10 ^-3 gm /cm^3
So density of mercury = 1.36 x 10^4 x 10^-3 gm /cc = 13.6 gm /cc
