Final answer:
The formula weight of ammonium fluoride (NH4F) is the sum of the relative atomic masses of its constituent atoms, totaling 37.04 amu.
Step-by-step explanation:
The formula weight of a compound is determined by summing the relative atomic masses of its constituent atoms. In the case of ammonium fluoride (NH4F), the formula weight is calculated by considering one nitrogen (N) atom, four hydrogen (H) atoms, and one fluorine (F) atom. The atomic mass of nitrogen is 14.00 atomic mass units (amu), hydrogen is 1.01 amu (four times for four atoms), and fluorine is 19.00 amu.
Adding these values together, the formula weight of NH4F is 37.04 amu. This calculation provides insight into the mass of one mole of NH4F molecules. Formula weight is a crucial concept in chemistry, aiding in various calculations such as molar mass and stoichiometry.
