Identify the given information: the amount of substance is 0.500 moles of N\_2O\_5, and Avogadro's number (N\_A) is 6.022 \(\times\) 10^{23} molecules/mol.
Recall that the number of molecules (N) can be found by multiplying the number of moles (n) by Avogadro's number (N\_A):
\[N = n \times N\_A\]
Substitute the given values into the formula:
\[N = 0.500 \text{ moles} \times 6.022 \times 10^{23} \text{ molecules/mol}\]
Perform the multiplication to find the total number of molecules present in 0.500 moles of N\_2O\_5.
