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 $6.022\times 10^{23}$ at atoms/molecules.

So, number of moles in $5.4\times 10^{24}$ molecules are :

$n = \dfrac{5.4\times 10^{24}}{6.022\times 10^{23}}\\\\n = 8.97 \ moles$

Therefore, number of moles are 8.97 .
