You need a composition book or a spiral bound notebook

Write on the right side and keep the left side for diagrams, graphs, tables, and pictures.

Data/Results

Percent Composition of Hydrates

In this lab you will find the percent composition of a hydrate and determine its molecular formula. You need to review section 3.6 Stoichiometry.

Heat for 7 minutes

About 1 g

Sample calculations are given below:

Density of Liquids

In this lab, you will determine the density of liquids.

Density of Liquids

Purpose The purpose of this lab is to measure the accuracy of the graduated cylinders and to determine the densities of liquids.

Results Graph your data. Questions What can you conclude from your observations. About the accuracy of the graduated cylinders? Explain using the data from your graph/slopes.
