Question

What is the mass of $3$ moles of calcium chloride, $CaC{l_2}$ ?

Answer 1

The SI base unit of mass is the kilogram. In physical science, mass isn't equivalent to weight, despite the fact that mass is regularly dictated by estimating the item's weight utilizing a spring scale, instead of an equilibrium scale contrasting it straightforwardly and known masses.

Complete step by step answer:
In science, we have to see the molar mass of a synthetic compound is characterized as the mass of an example of that compound partitioned by the measure of substance around there, estimated in moles. It is the mass of one mole of the substance or $6.022 \times {10^{23}}$ particles, communicated in grams. The molar mass is a mass, not subatomic, property of a substance. The molar mass is a normal of numerous cases of the compound, which frequently differ in mass because of the presence of isotopes.
In the given details, we have to calculate the mass of three moles of $CaC{l_2}$ .
By using the following formula,
$n = \dfrac{m}{M}$
Where,
The number of moles is represented as n, the mass is represented as m, and the molar mass is represented as M.
The molar mass of $CaC{l_2} = 110.98g/mol$
The number of moles = $3$
Applying all the values in the following rewritten equation,
$m = n \times M = \left( {3mol \times 110.98g/mol} \right)$
Therefore,
$mass = 332.9g$ .

Note: Calcium chloride is an inorganic compound, a salt with the substance recipe $CaC{l_2}$ . It is a white-shaded glasslike strong at room temperature, and it is exceptionally solvent in water. It tends to be made by killing hydrochloric corrosive with calcium hydroxide.
