Answer: 0.5mol

Explanation:

No of molecules = 3.01*10(23)

Avogadro's number = 6.022*10(23)

no of moles = No of molecules/Avogadro's number

No of moles =3.01*10(23)/6.022*10(23)

No of moles = 0.5mol

Answer:0.5 mole CHClF2

Explanation: Divide the molecules of CHClF2 to the Avogadro's number.

3.01x10²³ molecule CHClF2 x 1 mole CHClF2 / 6.022x10²³ molecules CHClF2

= 0.5 mole CHClF2
