Question

Calculate the number of neutrons present in 12×10^25 atoms of oxygen.

Answer 1

now to calculate the number of neutrons in 12 x 10 raised to the power 25 atoms of oxygen, calculate the number of neutronsin 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. Now multiply it with 2 x 10 raised to the power 2 to get the answer.
