N subscript 2 space space space space space space space space space space space plus space space space space space space 3 H subscript 2 space space space space space space space space space space space space rightwards arrow space space space space space space space space space space 2 N H subscript 3
0.2 minus x space space space space space space space space space space space 0.6 minus 3 x space space space space space space space space space space space space space space space space space space space space space space space 2 x

0.2 minus x plus 0.6 minus 3 x equals 60 over 100 cross times left parenthesis 0.6 plus 0.2 right parenthesis
x equals 0.08

n subscript 1 space equals 0.2 plus 0.6 equals 0.8
n subscript 2 equals left parenthesis space 0.2 minus 0.008 right parenthesis plus left parenthesis 0.6 minus 3 cross times 0.08 right parenthesis plus 2 cross times 0.004
space space space space space equals 0.64

fraction numerator F i n a l space m o l e s over denominator I n i t i t a l space m o l e s end fraction equals fraction numerator 0.64 over denominator 0.8 end fraction equals 4 over 5
