Question

How many moles are in 5.4x1024 molecules of C4H2F7I, heptafluoro-1-iodobutane? Group of answer choices

Answer 1

Given :

Number of molecules of
`C_4H_2F_7I`.

To Find :

How many moles are in given number of molecules.

Solution :

We know, in 1 moles of any element/compound contains
`6.022* 10^(23)` at atoms/molecules.

So, number of moles in
`5.4* 10^(24)` molecules are :

`n = (5.4* 10^(24))/(6.022* 10^(23))\\\\n = 8.97 \ moles`

Therefore, number of moles are 8.97 .
