For covalent substances, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now p...
Molar mass is calculated as a total of the atomic masses of all atoms that are present in a given compound. The atomic masses can be found in the periodic table. What is the formula to find molar mass? The molar mass is calculated as the product of mass and moles. Molar mass = Ma...

Find the gram formula mass of 1 moles of KAl(SO4)2· 12H2O. Remember, multiply the values of atomic mass units of atoms times their subscripts. Coefficients are multiplied by everything that follows. For this example, that means there are 2 sulfate anions based on the subscript and there ...
It is often represented in terms of ‘grams per mole’ (g/mol). However, the SI unit of this quantity is kg/mol. Molar mass can be represented by the following formula: Molar mass of a Substance = (Mass of the Substance in grams)/(Number of Moles) For example, the molar mass of...
multiply both the values. one mole consists of avogadro number of atoms. if you know the quantity of mole, it can be converted into grams and vice versa. the formula for moles to grams is given by example 1 – calculate the mass in grams of 3.6 mol of h 2 so 4 . ...
is an initial step in chemistry experiments where we first compute for the required amounts of reagents and solvents for the reaction. We can solve for the mass of the reagent by considering the number of moles for a required solution and then multip...
