Answer:
0.29
Explanation:
The bottle contain 28 % by mass ammonia and ( 100 - 28)% remaining water
molar mass of ammonia = 17.031 g/mol
molar mass of water = 18.01528 g/mol
mole of ammonia present = 28 / 17 .031 = 1.64 mol
mole of water present = 72 / 18.01528 = 4 mol
mole fraction of ammonia = 1.64 / ( 4 + 1.64) = 0.29
