Question

The total number of protons,electrons,and neutrons in 12g of C-12 is

Answer 1

Answer: total number is 3×6×(6.02×10^23)= 1.836×10^25

Explanation:

C-12 means one atom has 6 protons, 6 electrons and 6 neutrons.

Again 12g C-12 means 1mile of C-12 that means (6.02×10^23) C-12 atoms

1mol C-12 contains 6×(6.02×10^23) protons

6×(6.02×10^23) electrons

6×(6.02×10^23) neutrons

Total number of protons, electrons and neutrons is sum of the individual numbers which is equal to (1.0836×10^25)
