Answer 2

Hi there,

☆ Given

● N -3 anion valency electrons are 8e

● Sample mass of N anions is 4.2

● Atomic mass of N is 14

● NA avogadros no.

◇ First calculate no of moles

4.2 ÷ 14 = 0.3 mol

◇ Number of ions is moles × NA

So N anions are 0.3 NA ion

◇ Number of valency eletrons are

0.3 NA × 8e = 2.4NA
