Solution :

Given `M=2xx10^(30) kg, r=7xx10^(8) m` <br> `:.` Volume of sun `=4//3 pi r^(3) xx3.14xx(7xx10^(8))^(3)=1.437xx10^(27) m^(3)` <br> As `p=M//V," ":. P=2xx10^(30)//1.437xx10^(27)=1391.8 kg m^(-3)=1.4xx10^(3) kg m^(-3)` <br> Mass density of sun is in the range of mass densities of solids/liquids and not gases.
