Question

Two nuclei have their mass number in the ratio of 1:3 the ratio of their nuclear densities would be ?​

Answer 1

Answer:

1.1

Explanation:

Ratio of mass number in the nuclei = 1:3 (Given)

Nuclear density is defined as the density of the nucleus of an atom, thus

Density = mass/volume

Therefore d1 = m1/v d2 = m2/v

Since, the nuclear density is same for all the nuclei and is independent of the mass ratio, therefore -

d1/d2=m1/v/m2/v =m1/m2

p1 : p2 = 1:1

Answer 2

Explanation:

1:1

d=m/v = mA/ 4/3πR³

R=rA⅓

d= ml/4/3πr3

density is independent on mass
