what is the difference between formula weight and molecular weight?
151232
The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. The molecular mass (molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.

The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass.

Weight, or W, is a product of mass or M and gravity or G, which leads to the following equation: W = M & G. In addition, mass and volume -- V -- are related by density or D, which measures the mass of a substance per unit volume via the following equation: D = M/V.

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. ... Mass is denoted using m or M. Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity.

Molecular weight is the mass of a molecule of a substance. ... The units for molecular weight are atomic mass units (amu). Molar mass is the mass of one mole of a substance. Molar mass is reported in grams per mole or g/mol.

Explanation: When we write "formula mass", we usually mean the mass associated with 1 mole of such a formula; i.e. Avogadro's number of such a formula. Molar mass is the same thing: Avogadro's number of whatever stuff you have.

Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. ... A molecular formula is not a chemical name, and it contains no words. Although a molecular formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula.

Formula weight (FW), in chemistry, the sum of the atomic weights of all atoms appearing in a given chemical formula.

The mass, in grams, of 1 mole of a molecular compound is called the gram-molecular weight. It is numericaly equal to the molecular weight.

The empirical formula is by definition the simplest whole number ratio defining constituent atoms in a species. The molecular formula is always a whole number ratio of the empirical formula. Molecular formula = (Empirical formula)×n .

When we write "formula mass", we usually mean the mass associated with 1 mole of such a formula; i.e. Avogadro's number of such a formula. Molar mass is the same thing: Avogadro's number of whatever stuff you have. The ability to successfully calculate equivalent masses of compounds is vital to success in Chemistry.

Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass. The only difference is that gram molecular mass specifies the mass unit to be used. Gram molecular mass may be reported in grams or grams per mole (g/mol).

Molecular formulas give the kind and number of atoms of each element present in a molecular compound. In many cases, the molecular formula is the same as the empirical formula. The molecular formula of methane is CH4 and because it contains only one carbon atom and four hydrogen, that is also its empirical formula.

From the formula and the atomic mass of the atoms you can find the formula weight or molecular mass for the compound. To calculate the formula weight for a compound we will select the atomic mass of each of the elements in the compound from the periodic table, multiply by the number of atoms, and sum the result.

The atomic weight of a chemical element is the weight of N0 atoms of it. The atomic weights of the elements are included in the periodic table of the elements. ... The molecular weight of a molecule is equal to the sum of the atomic weights of its constituting atoms.

Gram formula mass. the amount of that compound that has the same mass in grams as the formula mass in atomic mass unit. Part/Whole. Coefficient. The number before that gets applied to all the molecules after it 2(xy) 2 is the coefficient and xy are the molecules.

The empirical formula is the representation of the relative number of each type of atom aka the lowest ratio. The molecular formula shows the absolute number of atoms of each element in a molecule. ... Divide each mole value by the smallest number of moles calculated.
