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.
