Question

How many Cl atoms are present in 2.16 moles of NC13?

Answer 1

Answer:Since one mole of MgCl2 consists of one mole of magnesium and two moles of chlorine, the mass of one mole of MgCl2 must be the sum of the masses of the elements. The mass of one mole of a substance is called the molar mass or molecular weight.

Explanation:

Answer 2

The number of of atoms of  Cl, in 2.16 moles of  $\bold {NCl_3}$ is $\bold {3.86x10^2^4}$.

Mole concept:

A mole is the number of atoms, ions and molecules that is equal to the $\bold {6.02x10^2^3}$.

In $\bold {NCl_3}$, the molar ratio of N and Cl is 1:3,

Thus,

The number of moles of Cl, in $\bold {NCl_3}$ is

2.16 x 3 = 6.48

Thus,

The number of atoms of  Cl, in 2.16 moles of  $\bold {NCl_3}$

6.48 x $\bold {6.02x10^2^3}$ = $\bold {3.86x10^2^4}$

Therefore, the number of of atoms of  Cl, in 2.16 moles of  $\bold {NCl_3}$ is $\bold {3.86x10^2^4}$.
