Answer 2

Answer:

Hello DUDE...... Your SOLUTION

Given,

Given,Mass of one atom of uranium = 3.9 * 10^-25

Given,Mass of one atom of uranium = 3.9 * 10^-25 kg 3.9 * 10^-22 g [1 kg = 1000 g)

Given,Mass of one atom of uranium = 3.9 * 10^-25 kg 3.9 * 10^-22 g [1 kg = 1000 g)Number of atoms in 1 g of uranium = 1/ 3.9*10^-22 = 2.56 * 10^21
