What is the weight of the formula?
The weight of the formula is the measurement used to identify how much a specific chemical compound weighs on the basis of its formula. For example, the weight of the formula of the oxygen molecule is about 32 grams per pier; This is because the oxygen molecule consists of two oxygen atoms and each oxygen atom weighs approximately 16 grams per pier. The weight of the formula is usually calculated from the molecular formula, which is the lowest number of atoms needed for the molecule. It is also known as an empirical formula.
The weight of the formula describes the molecular weight of the compound. The molecular weight is determined by the distribution of the number of grams of a specific chemical by the number of moths of a specific chemical. Mole is a constant that determines how many molecules are present in a specific amount of substance. This is called Avogadrovo number and is about 6.02 × 10^23 molecules or atoms. This means 16 grams of oxygen containing 6.02 × 10^23 oxygen atoms. Similarly, one sodium atom weighs about 23 grams. This means that 23 grams of sodium will contain 6.02 × 10^23 atomssodium.
In terms of the weight of the formula, the number of molds of the unknown sample may be determined by weighing the sample and using the known weight of the formula. For example, water has a molecular weight of 18 grams per mol. If the amount of water in the sample has a weight of 30 grams, then the number of moths in the compound is located by a division of 30 grams of 18 grams per pier. The answer is about 1.67 moths of water.
The calculation can be checked by determining that the moths appear to correlate with the number of grams. For example, if one moth of water has 18 grams, then it will have a sample with 30 grams of water, which is about 60 percent heavier, more water molecules. The weight of the formula can also be used to use the ratio of each atom in the molecule.
In general, the weight of the formula is used to calculate the percentage of weight, which is the amount of weight, each atom contributes to the overall molecule. It is usually determined by distributing the weight of an individual atom with the total weight of the molecules and then multiplying by 100. For exampleThe water has a total molecular weight of 18. The percentage of this weight, which is attributed to oxygen, is about 89 percent.
