# Solution: Calculate ΔSfus and ΔSvap for Na.

###### Problem

Calculate ΔSfus and ΔSvap for Na.

###### Solution

We’re being asked to calculate the ΔSfus and ΔSvap for Na.

We can calculate the entropy (ΔS) using the following equation:

$\overline{){\mathbf{∆}}{\mathbf{S}}{\mathbf{=}}\frac{\mathbf{∆}\mathbf{H}}{\mathbf{T}}}$

ΔS = entropy, J/mol•K
ΔH = enthalpy, J
T = temperature, K
