Question #781c0

Answer 1

`0.275 mols N_2`

Explanation:

`N_2` `+ 3H_2` `to` `2NH_3`

It can be seen from the balanced equation that:

`2` moles of `NH_3` are produced by number of moles of `N_2` `=` `1 mol`

`0.55` moles of `NH_3` are produced by number of moles of `N_2`

`=` `(1mol N_2)/(2 mol NH_3)` `xx` `0.55 mol NH_3`

`= 0.275 mols N_2`
