Answer:

3.18*10^24 molecules

Step-by-step explanation:

Since 1 mole of any substance consists of 6.022 × 10²³ molecules, simply do


(5.45 Moles)/(1)*(6.022*10^23 molecules)/(1 mole)=3.18199*10^24 molecules.

However, remember to include sig figs (3) and round it to 3.18*10^24 molecules

Hope this helps :)
