The mass of compound is given. By using the mass, the number of phosphorous atoms present in each of the compound given in exercise 52 is to be determined. Concept introduction: The atomic mass is defined as the sum of number of protons and number of neutrons. Molar mass of a substance is defined as the mass of the substance in gram of one mole of that compound. The molar mass of any compound can be calculated by adding of atomic weight of individual atoms present in it. The amount of substance containing 12 g of pure carbon is called a mole. One mole of atoms always contains 6 .022 × 10 23 molecules. The number of molecules in one mole is also called Avogadro’s number . To determine : The number of phosphorous ( P ) atoms in 1 .00 g of P 4 O 6 .
