Lab‚ Week # 1 BALANCE LAB Introduction The purpose of this lab is to learn how to utilize two different balances to find the mass of different chemicals in the ChemLab program. A balance is an instrument used to determine the mass of a chemical. To accomplish this we use direct weighing and weighing by difference on both the centigram and electronic balances. Equipment 1 Centigram Balances 1 Electronic Balance 1 100ml Beakers 5 Copper Slugs 2 Unknown Weights (Label # 1‚ # 2)

Molar Mass Lab 3.09 Molar Mass of Compounds Purpose: The purpose of this experiment is to determine the formula of a copper sulfate hydrate by heating it up. Materials: Hydrate‚ crucible‚ balance‚ Bunsen burner and scale Procedure: First you measure the mass of the empty crucible and record that mass. Then you should fill the crucible with 3-5 scoops of the hydrate and record that mass as well. Heat the hydrate filled crucible above the Bunsen burner for 10 minutes for all f the water to evaporate

Title: Calculating the Atomic Mass of “Pennium” Purpose: The purpose of this lab is to calculate the atomic mass of “pennium” using pennies made before 1982 and pennies made 1982 or after. Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny. Procedure: 1. Obtain a bag of pennies 2. Determine the total number of pennies in the bag. Record the value. 3. Sort the pennies by date into 2 piles. One pile should consist
