Homework Statement
Calculate the Debye temperature for gold
Homework Equations
$$Θ_D = \hbar \frac{v_s}{k_b} \sqrt[3]{6π^2 \frac{N}{V}}$$
Speed of sound in gold: $$v_s=3240 m/s$$
The Attempt at a Solution
I used the equation for ΘD and for the concentration I used the value for atom density that I calculated for gold 5.9*10^28m^-3. I also checked this atom density for gold on the internet and I found the same value. However, I got that the Debye temperature for gold is 375.52 K and a tabular value for gold is 165 K.
Can someone please tell me where I made the mistake in my calculation and these formulas?
