Answer: D) 2.82

Reasoning: There are 35.453 grams in a single mole.

So divide 100 by 35.453

100/35.453=2.82063577

Rounded 2.82063577 equals 2.82

There are 2.82 moles of chlorine in the 100 gram of chlorine. A mole is a unit of measurement that is used for very tiny particles such as atoms, ions, and molecules.

What is Mole Concept?

  • A mole is a unit of measurement that is used for very tiny particles such as atoms, ions, and molecules.
  • 1 mole is equal to the Avogadro's constant that is [tex]6.2\times 10^{23}[/tex].

The number of moles can be calculated by the formula,

[tex]n = \dfrac wm[/tex]

Where,

[tex]n[/tex]- number of moles

[tex]w[/tex] - given mass of chlorine

[tex]m[/tex] - molar mass of the chlorine

Put the values in the formula,

[tex]n = \dfrac {100}{35.45}\\\\n = 2.82 \rm \ g[/tex]

Therefore, there are 2.82 moles of chlorine in the 100 gram of chlorine.
