The Atomic Mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.
The gram molecular mass of hydrogen is 1 gram per mole.
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.

The gram molecular mass of lithium bromide is approximately 86.85 g/mol. This value is obtained by adding the atomic masses of lithium (6.94 g/mol) and bromine (79.90 g/mol).
The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.
The gram molecular mass of hydrogen is 1 gram per mole.
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
The gram molecular mass of glucose is 180 gram. Reason. The atomicity of glucose is 24.
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.

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.
The gram molecular mass of lithium bromide is approximately 86.85 g/mol. This value is obtained by adding the atomic masses of lithium (6.94 g/mol) and bromine (79.90 g/mol).
The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.
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.
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.
