The formula mass of a compound is the mass in grams of Avogadro's number (6.0221415 × 1023) of molecules.
For example NaCl (table salt) has a formula mass of 58.44277 (Na 22.9897, Cl 35.453) Avogadro's number of them weighs 58.44277 grams.
I am doing my chemistry homework now, and that's on of the questions, so if someone could provide an answer...that would be great!!!
Example for hydrochloric acid:
- Write the chemical formula of the compound: HCl
- Search the atomic masses of the elements
H = 1,00794
Cl = 35,454
- The molar mass is the sum (H + Cl): 36,460 94.
Formula mass represents the mass of an individual formula unit of a compound.
Formula mass represents the mass of an individual formula unit of a compound.
Apex lol
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Molecular mass and formula mass represent the mass of an individual molecule or formula unit of a compound.
The molar mass is the sum of atomic weights of elements in the molecule, expressed in grams.
The molecular formula
Organic formula is a formula that shows an organic compound and its molecular arrangement.
Yes, nitrogen monoxide is a molecular compound with a formula of NO.

The molecular formula specifies the actual number of atoms of each element in a molecule.
The molecular formula
Rearranges a molecule without changing the molecular formula
No; the compound with the formula NH4Br is an ionic compound.
Organic formula is a formula that shows an organic compound and its molecular arrangement.
This is the chemical formula (empirical formula) or the formula unit of this compound.
Yes, nitrogen monoxide is a molecular compound with a formula of NO.
No: The molecular formula is never smaller than the empirical formula.
The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.
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.
Ethanol is a compound. Its molecular formula is C2H5OH.
