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.

Answer:
Ok, so the process here is to convert the mass of H2 (hydrogen gas) to moles by dividing the mass by the molar mass of H2. Once you have the moles then you have to multiply by the STP (standard temperature and pressure) molar volume which should be 22.4.
Molar mass of H2 = (1.01)x2 = 2.02g/mol
19.3/2.02 = 9.55 moles
Now just multiply the moles by the molar volume
9.55 moles x 22.4 = 213.92 Litres of H2 are in 19.3g of H2
