Question

calculate the number of neutrons present in 12 x 10 raise to the power 25 atoms of oxygen​

Answer 1

Answer:

First of all, the atomic mass of oxygen is 16u. now to calculate the number of neutrons in 12 x 10 raised to the power 25 atoms of oxygen, calculate the number of neutrons in 1 atom of oxygen. now multiply it with 6 x 10 raised to the power 23 to get the number of neutrons in one mole of oxygen.
