#"Approx. 10g ammonia will be consumed."#

Explanation:

How many moles of nitric oxide reacted?

#n_"NO"# #=# #(27.8*g)/(30.01*g*mol^-1)# #=# #0.927*mol#.

Your stoichiometric equation CLEARLY shows that each equiv #NO# requires #2/3" equiv"# #"ammonia"# for the comproportionation to occur.

Thus #2/3xx0.927*molxx17.0337*g*mol^-1# #=# #??g#
