How many energy levels are prent in `3s` conduction hand of a single c

1.	How many energy levels are prent in `3s` conduction hand of a single crystal of sodium weighing `25.6 mg`?A. `7.01 xx 10^(20)`B. `7.01 xx 10^(23)`C. `6.02 xx 10^(23)`D. `6.68 xx 10^(20)`
Answer» Correct Answer - d `25.6 mg = (25.6)/(23)xx10^(-3)` mol `= (0.0256)/(23)N_(0)` sodium atoms Electrons in 3 s orbital in one sodium atom (conduction band) = 1. Thus total conduction bands (energy levels) `(0.0256)/(23)N_(0)` `= 6.68xx10^(20)`
