One mole of ANY ELEMENT is equal to Avagadro's number, and in this case it is still 6.02 x 10^23 atoms, so this time we must find the moles and this is easy, all we have to do is divide:
2.74/6.02 = 0.445 Moles of Flourine
The exponent 23 in this case follows the exponential law of division so that m^n/p^r = m/p^n - r
so then 23 - 23 = zero and we simply get 0.445 Moles.
