Question

The molecular formula of calcium chloride is $ CaCl_2 $ . What is the molecular weight of this drug?

Answer 1

Hint: Calcium chloride is a salt which is an inorganic compound. It has the chemical formula $ CaC{l_2} $ . At room temperature, It is a colorless crystalline solid. Molecular weight (which is also known as formula mass) of any molecule is calculated by multiplying the atomic mass of one atom by the total number of atoms in the molecule.

Complete answer:
Calcium chloride is a salt which is an inorganic compound. It has the chemical formula $ CaC{l_2} $ . At room temperature, it is a colorless crystalline solid. It is highly soluble in water.
Molecular weight (which is also known as formula mass) of any molecule is calculated by multiplying the atomic mass of one atom by the total number of atoms in the molecule.
Atomic mass is denoted by A. We know that, Atomic mass of Calcium is $ 40gmo{l^{ - 1}} $ and the atomic mass of chlorine atoms is $ 35.5gmo{l^{ - 1}} $ .
The chemical formula given is $ CaC{l_2} $ . Hence, we can see that there are two chlorine atoms and one calcium atom.
Therefore, the molecular weight of Calcium chloride is calculated as:-
 $ = (40 + (2 \times 35.5)) $
 $ = 111gmo{l^{ - 1}} $
Therefore, the molecular weight of this drug is $ 111gmo{l^{ - 1}} $ .

Note:
Calcium chloride is an inorganic salt which is highly soluble in water. It has many applications. This compound can be used for de-icing and dust control. Its anhydrous salt is hygroscopic, it is used as a desiccant. It is used to produce low-alkali cement. It is used as an additive in wastewater treatment plants and blast furnaces.
