1.

15. The total number of protons, electronsand neutrons in 12 g of 12C​

Answer»

Explanation:

total no.of e/p/n=(no.of e/p/n in a molecule)×(total no of molecue).FIRST we have to CALCULATE no.of moles in C ATOM solution =no.of moles in 12G of C atom is 12/12 =1mole .hence total no.of molecule is 6×10^23 now total no of e/p/n is 6×6×10^23=36×10^23......this is your answer
