What is the mass of 4 moles of fluorine atoms? ​

Vien, sometimes we make problems like this harder than they need to be. Suppose I asked you, “How many dozen wheels are on four dozen automobiles?” You would have no trouble answering 4 x 4 = 16 dozen.

A mole is just a quantity like a dozen. And in this case, instead of 4 wheels, each C2F6 molecule bears 6 fluorine atoms, right?

So 4 x 6 = 24 moles of fluorine atoms. You’ve got this, Vien!
