Determine the number of molecules present in 4.56 moles of nitrogen (n2).

To calculate the number of molecules, we can simply use this rule:
number of molecules = number of moles x Avogadro's number

In this problem, we have:
number of moles = 4.56 moles
Avogadro's number is a constant = 6.02 x 10^23

Substituting in the above equation, we can calculate the number of molecules as follows:
number of molecules = 4.56 x 6.02 x 10^23
                                  = 2.74512 x 10^24 molecules

100%sorry if i’m wronghope this good luck: )
