Percentage composition: Ammonia `(NH_(3))` si a pungent smelling very  soluble gas, given an alkatline solution  containing  ammonnium  hydoximate. It is used  as a refigerment  and for the  manufacture  fo fertilizers. Calculate  the mass percentage  fo the elements in ammnia. Strategy: We need the mass of an element in a given mass of compound. To get this information, we interpect  the formula  in molar terms  and then  convert  moles to masses. Every  molecule of ammonia always has the formula  `NH_(3),i.e., 1` mol of `NH_(3)` always contains 1 mol of `N` atoms and 3 mol of  `H` atoms.
