This is called a hypothesis.
Some of the substance may be boiled off into the air (depending on the experiment) and cannot be weighed after the experiment is finished.
The reason they would is because it is a lot safer.
Scientists repeat their experiments because to make sure that their results are correct.

He or she states the problemThe scientist forms a hypothesis, a possible solution to the problem. The simplest solution is often the best solution.Next, a scientist might want to perform a controlled experiment. A controlled experiment can give a scientist more information about his or hers hypothesis.Results are recorded and analyzed.Using the data the scientist can develop a conclusion.
There are various reasons. Here are some:They might be skeptical of the reliability or truth of what other scientists have claimed.They might be trying to understand the earlier results better.They might be hoping to extend the other scientist's results.They might be trying to determine whether there are limits to the applicability of the other scientist's results.
