From the relation R = R0A1/3, where R0 is a constant and A is the mass number of a nucleus, show that the nuclear matter density is nearly constant (i.e. independent of A).
The radius od a nucleus is given as R = R0A1/3 (A = mass number)
And, the density is given by =
Let m be average mass of the atom, hence Mass = mA
And volume =
Hence, 𝞺 = =
This is a constant independent of A. So, Nuclear density is a constant.

In a periodic table, the average atomic mass of magnesium is given as 24.312 u. The average value is based on their relative natural abundance on earth. The three isotopes and their masses are 2412Mg (23.98504u), 2512Mg (24.98584u) and 2612Mg (25.98259u). The natural abundance of 2412Mg is 78.99% by mass. Calculate the abundances of other two isotopes.NCERT - Physics Part-II
