Students will understand the ideal gas law

Experiment 7: Gas Law Goals 1. Students will understand the ideal gas law

2. Students will understand partial pressure 3. Students will understand limiting reagents

Objectives:

1. Students will be able to determine the identity of an unknown metal

2. Students will be able to use a gas collection tube

3. Students will be able to safely handle chemicals

4. Students will be able to do limiting reagent stoichiometry calculations

Introduction :

In this experiment you will be determining the identity of an unknown metal by determining the atomic mass and comparing your experimental results with the expected value. Obtaining accurate results will require taking a number of corrections into account.

Equipment:

1. Barometer (on the front wall)

2. Gas measuring tube (x8)

3. Buret Stand (x4)

4. Scissors

5. Thermometer, 0.1o C (x4)
