The molar mass of (NH4)3PO4 is 149,09 g.
The gram formula for potassium sulfite (K2SO3) is 158.27 g/mol.
H2O's molar mass is 18 g/mol.
The gram formula mass of sodium (Na) is approximately 23 grams per mole.
The gram formula mass of acetic acid (CH3COOH) is approximately 60.05 g/mol.
To determine the molecular formula from the empirical formula and gram formula mass, first calculate the empirical formula mass of C4H9 (4 carbons + 9 hydrogens). Then, divide the gram formula mass by the empirical formula mass to find the ratio. Finally, multiply the subscripts in the empirical formula by this ratio to get the molecular formula, which in this case is C8H18.

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).
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
The atomic mass number of nitrogen is 14.0
From the Periodic Table The Atomic mass of Nitrogen (N) is 14 The Atomic mass of Oxygen (O) is 16 Hence the gram formula mass of NO is 14 + 16 = 30 Now NO under certain circumstances can form N2O2 hence the gram formula mass of N2O2 = (2 x 14) + ( 2 x 16) = 28 + 32 = 60 However the empirical formula is the formula with the lowest ratio of atoms. Hence N2O2 lowest ration is NO # formula mass is 30 .
