Compound.La masa molar y el peso molecular de KCl (Cloruro De Potasio) es 74,551. ... Cloruro De Potasio Elemento Porcentaje de Masa Potasio 39.0983g Potasio 39.0983g Cloro 35 ... Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in KCl + NaCl: Molar Mass (g/mol) K (Potassium)K: 1, Cl: 1, O: 1. Then, lookup atomic weights for each element in periodic table: K: 39.0983, Cl: 35.453, O: 15.9994. Now, compute the sum of products of number of atoms to the …Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Steps to calculate molar massCompute Mass of Each Element. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in KClO3: Molar Mass (g/mol) K (Potassium) 1 × 39.0983 = 39.0983. Cl (Chlorine) .
