If the specific activity of carbon is 15.5 dpm/g today, what is the percentage abundance of 14C?
1) A 141 g sample of carbon from ancient wood is found to have an activity of 5.289 decays/min. a. How many half lives have elapsed since the tree was cut down? b. How many years have elapsed since the tree was cut down? would appreciate any help

Please help with pre-lab questions.
Pre-Lab Questions: 1. A sample of 2-butanol has a specific rotation of +3.25. Determine the optical purity (%ee) and percent composition of this sample (see Mohrig section 17.4). The specific rotation of pure (+)-2-butanol is +13.0°. 2. The equation for the formation of the diastereomeric salts is shown in the background information (performed in Part A of the procedure). Write this chemical equation in your notebook, then ALSO write a balanced equation for the formation...
