Question

the mass of 4 L of ethanol is 1680 g.calculate density in C.G.S and SI unit ​

Answer 1

Explanation:

1 L = 0.001 m^3 , so, 4L = 0.004 m^3 = 4000cm^3

now ,

density = mass/ volume

in cgs unit density will be (1680/4000) gm/cm^3

=0.42 gm/cm^3

in s.i unit density =(1.680kg/0.004m^3) =420 kg/ m^3
