Question

Two nuclei have mass numbers in the ratio 1: 2. What is the ratio of their nuclear densities?

class 12
chapter:- Nuclei​

Answer 1

Answer:

Density=mass/volume

D=m/v

v=4/3πr^3

D1/D2=27/127×(r2/r1)^3

We know equation of radius

R=Ro×A^(1/3)

Where Ro is constant

A=mass no.

now,

D1/D2=27/125×A2/A1

D1/D2=27/125×125/27=1

$\frak \red (question$

What is the ratio of their nuclear densities?

ans:

The ratio of nuclear densities is 1. This is because nuclear density does not depends upon mass number.

Two nuclei have mass numbers in the ratio 1:2. What is the ratio of their nuclei densities ?

answer

Since Nuclear density is independent of mass number,

so ratio of their nuclear densities is 1:1

hope its help u didi
