The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
The correct chemical formula for a molecule of N3 and H+ would be NH4+, forming the ammonium ion.

The formula mass of a molecule made up of only one atom is simply the atomic mass of that element. This mass is typically expressed in atomic mass units (amu) and can be found on the periodic table. For example, the formula mass of a helium atom (He) is approximately 4.00 amu, which corresponds to its atomic mass.
the empirical formula and the molar mass
To determine the gram mass of an element in a molecule, you first need to know the molecular formula of the molecule, which indicates the number of each type of atom present. Calculate the molar mass of the entire molecule based on the atomic weights of its constituent elements. Then, find the molar mass contribution of the specific element by multiplying its atomic weight by the number of atoms of that element in the formula. Finally, use the ratio of the element's molar mass to the total molar mass of the molecule and multiply by the total gram mass of the molecule to find the gram mass of the element.
A structural formula
The correct chemical formula for a molecule of N3 and H+ would be NH4+, forming the ammonium ion.
The formula mass of the ammonium ion, NH4+, is calculated by adding the atomic masses of the elements in the formula. For NH4+, the atomic mass of nitrogen (N) is 14.01 and the atomic mass of hydrogen (H) is 1.01. Therefore, the formula mass is 14.01 + (4 x 1.01) = 18.05 g/mol.
The formula for hydronium ion is H3O+. It is formed when a water molecule gains a proton (H+) through protonation.
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
The formula for Hydronium Ion is H30+. Hydronium Ion is an Aqueous Solution and is also considered as a bare nucleus.
This formula is for citrate ion; the mass is 191,1 g.
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol

A molecular ion is formed when a molecule gains or loses an electron, resulting in an ion with a net positive or negative charge. This can occur through processes such as electron impact ionization, chemical ionization, or electrospray ionization in mass spectrometry. The resulting molecular ion retains the same chemical formula as the neutral molecule but has a different charge.
The grand formula mass is the sum of the masses of all the atoms in a single molecule of a compound, including all elements present in that compound. It is calculated by adding up the atomic masses of each element involved in the molecule.
The formula mass of a molecule made up of only one atom is simply the atomic mass of that element. This mass is typically expressed in atomic mass units (amu) and can be found on the periodic table. For example, the formula mass of a helium atom (He) is approximately 4.00 amu, which corresponds to its atomic mass.
