In order to attain equilibrium, you need to have a minimum of a minute amount of PH3BCl3 (s) left in the flask. Alternatively, it will be all spend before you attain equilibrium concentration. Let PH3BCl3 (s) be called C. Molecular weight of C is 151.

4.32x10^-2molC/1L x 0.25 L x 151gC/1molC = 1.63 g C is the answer.
