We use high precision lattice simulations to calculate the plaquette expectation value in three-dimensional SU(N-c) gauge theory for N-c=2, 3, 4, 5, 8. Using these results, we study the N-c-dependence of the first non-perturbative coefficient in the weak-coupling expansion of hot QCD. We demonstrate that, in the limit of large Nc, the functional form of the plaquette expectation value with ultraviolet divergences subtracted is 15.9(2)-44( 2)/N-c(2).
