### Effect of Leaving the Stopper Off During Weighing**Question:** What would be the effect on your calculated molecular weight of p-dichlorobenzene if your lab partner left the stopper off of the apparatus while you were weighing the solid p-dichlorobenzene? Explain in detail what would happen if this occurred and how it would affect your result.**Explanation:**Leaving the stopper off during the weighing of p-dichlorobenzene can lead to the volatilization of the substance, resulting in a loss of mass. This loss would cause an underestimation of the actual mass of p-dichlorobenzene, leading to errors in the calculation of its molecular weight. The perceived molecular weight would be higher than the true value since the calculations would be based on a lesser amount of substance than originally intended. Accurate weighing is crucial for precise measurement and calculations in experimental procedures.

Volatile compounds when kept open while weighing, some of the mass is lost as vapor and the mass…
