Importance of Molar Mass
In chemistry, the molar mass of a compound is a critical property that determines its behavior and reactivity. The molar mass is the sum of the atomic masses of all the atoms present in a molecule. It is expressed in units of grams per mole (g/mol) and is a fundamental concept in stoichiometry, the branch of chemistry that deals with the quantitative relationships between reactants and products.
PbCl2 Molar Mass
So, what is the molar mass of PbCl2? To calculate the molar mass of PbCl2, we need to sum the atomic masses of lead (Pb) and chlorine (Cl). The atomic mass of lead is 207.2 g/mol, while the atomic mass of chlorine is 35.45 g/mol.
PbCl2 molar mass = (1 x atomic mass of Pb) + (2 x atomic mass of Cl) = (1 x 207.2 g/mol) + (2 x 35.45 g/mol) = 207.2 g/mol + 70.9 g/mol = 278.1 g/mol
Therefore, the molar mass of PbCl2 is approximately 278.1 g/mol.
