What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?
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.

What is the gram molecular mass of lithium bromide?
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).
How the moleculer formula of a compound is calculated if its emperical formula is known?
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.

How do you convert from molecular mass to grams per mole?
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.

What is the molecular formula of a compound with an empirical formula of C4H9 and a gram formula mass of 114 grams mole?
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.
What is the word equation of calcium with hydrochloric acid?
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.
What is the gram molecular mass of sulfur molecule?
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.
