Measure and record its mass, and then place the filter paper on the funnel. Collect some gas from the exit of combustion tube with test tube. The general procedure is to use laboratory techniques to determine the mass of each element in the compound. The mass of the crucible, lid and compound was recorded. They should divide mass by the atomic mass for each element. In part 1 of the experiment the Average Density of Unknown Solid was 8. A compound, no matter how it is formed, always contains the same elements in the same proportion by weight.
