12.4 moles of fluorine atoms are in a sample of fluorine that contains 7.45 x 10²⁴ fluorine atoms. Details about number of moles can be found below.
The number of moles in a molecule of a substance can be calculated by dividing the number of molecules by Avogadro's number.
According to this question, a sample of fluorine that contains 7.45 x 10²⁴ fluorine atoms. The number of moles in this sample can be calculated as follows:
no of moles = 7.45 × 10²⁴ ÷ 6.02 × 10²³
no of moles = 1.24 × 10¹
no of moles = 12.4moles
Therefore, 12.4 moles of fluorine atoms are in a sample of fluorine that contains 7.45 x 10²⁴ fluorine atoms.
