Question

How many possible microstates are there for 1 mol of H2O (l) at room temperature? (Use S◦ = 188.8 J/K mol.)

science chemistry

Answer 1

Answer #1

For 1 mol

S = 188.8 J/K

then

$S = k_\mathrm{B} \ln W \!$

which is Boltzmann equation and

1.38065 × 10⁻²³ J/K.

W = number of microstates

then

188.8 = 1.38065 × 10⁻²³ * lnW

W = exp((188.8)/(1.38*10^-23)) = exp(1.36811*10^25)

# microstates = exp(1.36811*10^25)
