The formula for lithium sulphide is Li2S.
The chemical formula for sulfur is S, and for lithium it is Li.
The gram-formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit of the compound. For NO2, the gram-formula mass is calculated by adding the atomic mass of nitrogen (N) and two times the atomic mass of oxygen (O).
Li2s
Nitrogen hydride has the chemical formula of NH3 The gram formula mass of nitrogen is approximately 14.0 g/mole & the gram formula mass of hydrogen is approximately 1.0 g/mole In the chemical formula, you have 1 nitrogen atom and 3 hydrogen atoms 14.0 + 1.0 + 1.0 + 1.0 = 17.0 g/mole
