For this, assume ideal behavior for the molecules. So, in the problem, you are given: 

 $\sf \color{red}{Tempetaure ~[T] = 273.15~K}$
 $\sf \color{blue}{Pressure ~[P] = 1~atm}$
 $\sf \color{green}{Volume ~[V]= 22.4~L}$

So, you're going to use: $\sf \color{purple}{PV=nRT}$
Solve for $n$, which is moles (this is algebra, rearrange the formula to solve for what you want). Also, keep in mind you're gas constant, $\sf \color{orange}{8.314 \frac{L ~atm}{mol~K}}$

Once you have moles, use avogadro's number: $\sf \color{green}{6.022 \times 10^{23} \frac{molecules}{mole}}$ to find the amount there are.
