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)

The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome
