The ammonium ion has one nitrogen atom and four hydrogen atoms. Their atomic masses are 14 and 1 respectively. Therefore the RMM of the ammonium ion s 14+4x1=18.
The relative molecular mass of CaCO3 (calcium carbonate) is approximately 100.09 g/mol.
Molecular mass is the sum of the atomic masses of all the atoms in a molecule. It is usually expressed in atomic mass units (amu) or grams per mole (g/mol). Molecular mass is used to determine the mass of a substance in chemical reactions and stoichiometry calculations.

The molecular formula of ammonium carbonate is (NH4)2CO3. The molar mass of nitrogen in ammonium carbonate is 28.02 g/mol. The molar mass of ammonium carbonate is 96.09 g/mol. To calculate the mass percent of nitrogen in ammonium carbonate, you would divide the molar mass of nitrogen by the molar mass of the compound and multiply by 100. This gives a mass percent of nitrogen in ammonium carbonate of around 29.1%.
The molecular formula for Ammonium Sulphate is (NH4)2SO4.

The symbol Mr in chemistry stands for the relative molecular mass of a compound. It represents the average mass of a molecule of the compound compared to one-twelfth of the mass of an atom of carbon-12.
They are the calculated averages of all the isotopes of a particular element in accordance to their relative abundances, and hence is generally not an integer due to the mathematical division involved.
The molecular formula of the compound is NH4NO3, which is ammonium nitrate. This compound contains nitrogen, hydrogen, and oxygen elements, with a molecular mass of approximately 63.008 amu.
The molecular formula of ammonium bicarbonate is NH4HCO3. To find the mass percent of hydrogen (H) in it, we calculate the molar mass of hydrogen in the formula and divide it by the molar mass of the whole compound NH4HCO3, then multiply by 100. The mass percent of hydrogen in ammonium bicarbonate is approximately 5.9%.
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
