What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
What is the molecular formula of a compound given that molar mass of the compound is 30.04 gram and the empirical formula is NH?
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.
What are the sum of atomic masses of all atoms formula for a compound called?
It is called the molar mass of that compound. In other words, the total mass of all of the elements in a compound is equal to one mole of that compound.
How many H atoms are present in a chemical formula?
By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
