Question

What is the atomic mass of calcium chloride?

Answer 1

Hint: The mass of a molecule is measured in daltons and is called molecular mass. Because they contain various isotopes of an element, multiple molecules of the same chemical may have different molecular weights. The related quantity relative molecular mass is a unitless ratio of a molecule's mass to the unified atomic mass unit as defined by IUPAC. The molecular mass and relative molecular mass are not the same as the molar mass, but they are linked. The molar mass is stated in g/mol and is defined as the mass of a particular substance divided by the quantity of that substance.

Complete Step By Step Answer:
Calcium chloride is a salt with the chemical formula $ CaC{{l}_{2}} $ . It is an inorganic substance. At ambient temperature, it is a white crystalline solid that is readily soluble in water. It's made by mixing calcium hydroxide with hydrochloric acid to neutralise it. $ CaC{{l}_{2}} $ is a hydrated solid having the general formula $ CaC{{l}_{2}}.{{\left( {{H}_{2}}O \right)}_{x}} $ , where x = 0, 1, 2, 4, and 6. De-icing and dust management are two of the most common applications for these chemicals. The anhydrous salt is used as a desiccant since it is hygroscopic.
To get the molar mass of a compound, use the periodic table to calculate the molar masses of each element individually.
Calcium and chlorine are the two elements in our instance. The molar masses of Ca (40.08g/mol) and Cl (35.45g/mol) must then be determined.
We can see from the chemical formula that there are two chlorine atoms, and the molar mass of 35.45g/mol only accounts for one Cl atom. The molar mass must be multiplied by two to account for both chlorine atoms:
 $ 2\times 35.45=\text{ }70.90\text{ } $
Now that we have the masses of calcium and both chlorine atoms, we can simply put them together to get the whole compound's molar mass, which is 110.98 g/mol.

Note:
Calcium chloride is used to speed up the early setting of concrete, however chloride ions cause steel rebar to corrode, therefore it should not be used in reinforced concrete. This may also be done using the anhydrous form of calcium chloride, which can be used to determine the moisture content of concrete. Calcium chloride is used as a thinner in fabric softeners and as an ingredient in plastics and fire extinguishers. It is also used in blast furnaces to reduce scaffolding (clumping and adhesion of elements that hinder the furnace charge from descending).
