Formula weight: Formula weight, in chemistry, the sum of the atomic weights of all atoms appearing in a given chemical formula. It is generally applied to a substance that does not consist of individual molecules, such as the ionic compound sodium chloride. Such a substance is customarily represented by a

The formula mass and molecular mass of water (H 2 O) are one and the same, while the formula and molecular mass of glucose are different from each other. The formula mass (formula weight) of glucose is 30 (either no units or else grams per mole), while the molecular mass (molecular weight) is 180.156 g/mol.

en.wikipedia.org/wiki/Weight

This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration. In 1901, the 3rd General Conference on Weights and Measures (CGPM) established this as their official definition of weight:

Use the formula "w = m x g" to convert weight into mass. Weight is defined as the force of gravity on an object. Scientists put that sentence into an equation by writing w = m x g, or w = mg. Since weight is a force, scientists also write the equation as F = mg. F = symbol for weight, measured in Newtons, N.

formula weight, in chemistry, a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a formula by the number of atoms of that element present in the formula, and then adding all of these products together. For example, the formula weight of water (H 2 O) is two times the atomic weight of hydrogen plus one times the atomic weight of oxygen.

Gravity, Mass & Weight. The questions on this page test your ability to use the formula: Weight = Mass × Gravity. You may also wish to learn the formula as: W = mg. Question 1. The strength of gravity at the Earth's surface is 10 newtons per kilogram. Calculate the weight of a car with a mass of 1500 kg.

Formula Weights. A simple but very important skill that you will be called upon to do many, many times during this course is to calculate the formula weight of a chemical based on its formula. You can do that very easily as long as you know the formula of the chemical with which you are dealing.

A related term you should know is relative formula mass (relative formula weight). This simply means the calculation is performed using relative atomic weight values for the elements, which are based on the natural isotopic ratio of elements found in Earth's atmosphere and crust.
