How many electrons , protons and neutrons are there in 12g of ""_(6)C^(12)and in 14g of ""_(6)C^(14) (Take Avogadro number N = 6xx 10^(23) ) |

Answer» Solution :The number of atoms in 12 G of `""_(6)C^(12)=` Avogadro number `= 6 xx10^(23)` The number of electrons in 12 g of `""_(6)C^(12)= 6 xx6xx10^(23)` `= 36 xx10^(23)` The number of protons in 12 g of `""_(6)C^(12)= 36 xx10^(23)` The number of NEUTRONS in 12 g of `""_(6)C^(12)` `= (A-Z) xx 6 xx 10^(23) = 6xx 6 xx 10^(23)= 36 xx10^(23)` Similarly number of electrons in 14 g of `""_(6)C^(14)= 36 xx10^(23)` Number of protons in 14 g of `""_(6)C^(12) = 36 xx10^(23)` Number of neutrons in 14 g of `""_(6)C^(14) = (A-Z) xx 6 xx10^(23) ` `= (14 -6) xx 6 xx10^(23)= 48 xx 10^(23)` |
