## Homework Statement

I'm attempting to calculate the translational entropy for N

_{2}and I get a value of 207.8 J/Kmol. The tabulated value is given as 150.4 and I am stumped as to why the decrepancy.

T = 298.15 K and P = 0.99 atm and V = 24.8 L

R = 8.314 J/Kmol[/B]

## Homework Equations

S

_{trans}= R ln[(2ΠmkT/h

^{2})

^{3/2}*V*e

^{5/2}/N

_{a}][/B]

## The Attempt at a Solution

I plugged in all the correct(?) values and cannot figure out what I'm doing wrong.
