Because they are not expensive, can assure a convenable sealing, are flexible, resist a long time, many reagents doesn't attack rubber, can support temperature in a wide range, the contaminatiom from the rubber is minimal, etc.
Of course rubber stoppers are not recommended for all experiments.

What are the laboratory apparatus of rubber plug?
The main reason for a rubber stopper is to stop gas or liquid from coming out of the container. Rubber stoppers can also prevent contamination of samples by keeping the laboratory glassware safe.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
rubber stopper burst up because it has strong afinity with hydrogen
What is the function of a rubber bung?
A rubber bung (also called rubber stopper) is used in the laboratories for test tubes, flasks (made of glass usually). Bungs also used by winery industry for the wine bottles. A bung must fill well as a stopper. The bungs are of many sizes. Rubber bung can have one or more hole(s) for plugging in tube depending on the specification of the procedures. In chemical laboratory, to prevent the liquid chemical leaks or escape the container, we need the rubber bung that fit tightly to the container's open, therefore, the dimension of the rubber bung is concerned. These are some of the sizes that are commonly seen in chemical laboratory

Would a rubber stopper float in water?
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float in water?
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?
Since the difference in volume corresponds to the volume of the stopper, the volume of the stopper=30.9-25=5.9ml Thus density of the rubber stopper=mass/vol=(8.46/5.9)g/ml
Why is it important to touch a charged object to the metal rod of an electroscope and not to the rubber stopper?
it is important because if you don't and touch the rubber stopper it will not show if it is positive.
What is the average life expectancy of a rubber stopper?
This is very variable and depends on: - type of rubber - temperature - pressure on the stopper - the liquid in contact - other conditions of use
