Why must the stopper at the top of the separatory funnel be removed before liquid can be withdrawn through the stopcock?
If the stopper is left in place while liquid is draining a vacuum will be created in the separatory funnel and outside air will try to get in. The only way it can do this is through the opening that the liquid is trying to leave. The air pushes against the liquid and will greatly reduce or even stop its flow. If the stopper is removed no vacuum is created because the air can easily get in the top of the funnel.

When a rubber stopper has a mass of 8.46g was immersed in a graduated cylinder containing 25 ml of water the water rose to 30.9 ml Calculate the densityof the rubber stopper?
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.

What kind of apparatus is separatory funnel?
Its just a simple glass jar with a cap on the top and a nozzle+stopcock on the bottom. Its mainly for extracting things from a polar solution to a nonpolar solution(or the other way around). You pour out the bottom layer through the nozzle, and the top layer you pour out the top, to avoid getting impurities that are in still in the nozzle from just pouring out the bottom layer.
