Alpha particles produced by radioactive decay eventually pick up electrons from their surroundings to form helium atoms. Calculate the volume (in ml.) of He collected at STP when 1.20 g of pure 226Ra is stored in a closed container for 162. years. (Assume that there are five alpha particles generated per 256 Raas it decays to 206 Pb. The half-life is approximately 1.60 x 10 years.) Round your answer to 2 significant digits. Note: Reference the Fundamental constants table for additional information.
