Question

calculate the total ions present in 4.2 gram of N3​

Answer 1

The no of moles of nitride ion in 4.2g is 4.2/14=0.3 mol. So the no of valence electrons is equal to 8x0.3xNa, where Na is avogadros no. whose value is (6.022x10^23). ... Mole of Nitrogen is 4.2/14=0.3. and valance electron of Nitride is 8 Because it has 10 electrons so electrons are like this (2,8).
