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.

Why do you think it is important to use the same blanace throughout the entire experiment?
Zepler [3.9K]

It is important to use the same balance throughout the entire experiment since the calibration of each balance is not the same and changing balances could result in a systematic error.

There are three types of errors that could affect the results of the experiment. The effect of random or indeterminate errors is hard to predict, its effect on the results of the experiment could be different every time. The second type of error is the systematic or determinate error, which causes a shift in results in a specific direction. The last type of error in an experiment is human error.

The type of error that could be related to the use of different balances throughout the experiment is the systematic error. Instruments could be a source of error especially if they are poorly calibrated. Also, analytical balances are calibrated differently which may result in inaccuracy in the weighing of chemicals.
