Which of the following contains gretest number of `N` atoms?A. `22.4 L` nitrogen gas at `STP`B. `500 mL` of `2.00 M NH_(3)`C. `1.00 mol` of `NH_(4)Cl`D. `6.02xx10^(23)` molecules of `NO_(2)` |
Answer» (`a`) `22.4 L N_(2)` gas at `STP=1 mol N_(2)` `=N_(0)` molecules of `N_(2)` `=2N_(0)` atoms of `N` (`b`) `(500xx2)/(1000)=1 mol` of `NH_(3)` `=N_(0)` molecules of `NH_(3)` `=N_(0)` atoms of `N` (`c`) `1 mol` of `NH_(4)Cl=N_(0)` atoms of `N` (`d`) `6.02xx10^(23) NO_(2)` molecules `=6.02xx10^(23)` atoms of `N` |
