Question

1. Indiana Jones discovers a skeleton lying in the catacombs of the building, and is wondering how old this person might be.  

   1. Indy can use carbon-14 to date the age of the skeleton, as it has a half life of about 5700 years. If the body originally contained 75g of carbon-l4, how long will it take for there to only be 30g of carbon-14 left?

   2. Assuming the body is 950 years old, how much carbon-14 will remain (assuming the starting amount is still 75g)?
