Which of the following contains maximum number of nitrogen atoms ?

1.	Which of the following contains maximum number of nitrogen atoms ?
Answer» `22.4 L` of `N_(2)` at STP 500 ML of `2.0 M NH_(3)` `6.02 xx 10^(23)` MOLECULES of `NO_(2)` 1.00 MOL of`NH_(4)Cl` SOLUTION :(A) 22.4 L of `N_(2)` at STP `~=` 1 mol of `N_(2) = 2` mol of N (B) 500 mL of 0.2 M `NH_(3) = 1 mol " of " NH_(3)` = 1 mol of N (C) `6.02 xx 10^(23)` molecules of `NO_(2) =` 1 mol of N (D) 1.00 mol of `NH_(4)Cl = 1` mol of N Thus (A) contains maximum number of N atom
