Expert Answer
It is a question based on stoichiometry. To solve this question, Firstly We will write chemical equation of formation of ammmonia (NH3).
 
space space space space straight N subscript 2 space space space space plus space space space 3 straight H subscript 2 rightwards arrow space space space 2 NH subscript 3
space
Number space of space moles space of space straight N subscript 2 equals 50 over 28 space space space equals 1.78

According space to space stoichiometry comma space

1 space mole space of space straight N subscript 2 space produces space 2 space moles space of space NH subscript 3

So comma space 1.78 space moles space of space straight N subscript 2 space will space produce equals space 1.78 cross times 2 equals 3.56 space moles space of space NH subscript 3

We space know space that comma space Number space of space moles equals fraction numerator Masss space in space grams over denominator Molar space mass end fraction

So comma space For space ammonia comma space space 3.56 equals fraction numerator Mass space of space Ammonia space over denominator 17 end fraction

Mass space of space Ammonia space equals 17 cross times 3.56 equals 60.52 space grams
