Question

How many atoms are in 1.50 moles of fluorine gas?

Answer 1

Fluorine gas is a diatomic molecule (two bonded atoms).

So multiply the moles by two and then by Avogadro's number:

(2)(1.50 mol)(6.02x10^23 atoms/mol) = 1.81x10^24 atoms

Answer 2

Answer: The number of atoms in given amount of fluorine gas are
`1.807* 10^(24)`

Step-by-step explanation:

We are given:

Moles of fluorine gas
`(F_2)` = 1.50 moles

1 mole of fluorine gas contains 2 moles of fluorine atoms

According to mole concept:

1 mole of a substance contains
`6.022* 10^(23)` number of particles

So, 1.50 moles of fluorine gas will contain
`(2* 1.5* 6.022* 10^(23))=1.807* 10^(24)` number of atoms.

Hence, the number of atoms in given amount of fluorine gas are
`1.807* 10^(24)`
