Hello!

$\large\boxed{5.33*10^{4} moles}$

Begin by converting $3.21 * 10^{28}$ molecules to moles using Avogadro's number:

$3.21*10^{28} moles* \frac{1 mol}{6.02*10^{23} moles} = \frac{3.21*10^{28} }{6.02*10x^{23} }moles$

Simplify:

$\frac{3.21*10^{28} }{6.02*10x^{23} }=0.53*10^{5} = 5.33*10^{4}$

Therefore, there are $5.33*10^{4}$ moles in $3.21*10^{28}$ molecules of $N_{2}$ .

As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase.

hope this helps
