The Chemical Formula of Calcium Chloride
Before discussing the molecular mass, let’s establish the chemical formula for calcium chloride. Calcium chloride is composed of one calcium (Ca) atom and two chlorine (Cl) atoms, making its chemical formula CaCl2. This formula indicates the relative proportions of each element in the compound.
Atomic Structure of Calcium and Chlorine
To understand calcium chloride’s molecular mass, we must account for the atomic masses of calcium (Ca) and chlorine (Cl). Calcium possesses an atomic number of 20 and an atomic mass of approximately 40.08 amu. Chlorine, having an atomic number of 17, has an atomic mass of around 35.45 amu. It’s important to note that these atomic masses are averages that consider the naturally occurring isotopes of each element.
Molecular Mass of Calcium Chloride (CaCl2)
To calculate the molecular mass of calcium chloride (CaCl2), we add the atomic masses of each element present in the compound:
Molecular Mass of CaCl2 = (Atomic Mass of Ca) + (2 x Atomic Mass of Cl) Molecular Mass of CaCl2 = (40.08 amu) + (2 x 35.45 amu) Molecular Mass of CaCl2 = 40.08 amu + 70.90 amu Molecular Mass of CaCl2 = 110.98 amu
So, the molecular mass of calcium chloride (CaCl2) is approximately 110.98 atomic mass units (amu).
