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.

Over geological time, an atom of 238U decays to a stable 206Pb atom in a series of eight alpha emissions, each ofwhich leads to the formation of one helium atom. A geochemist analyzes a rock and finds that it contains 9.0 ×1025cm3of helium (at 0°C and atmospheric pressure) pergram and 2.0 × 1027g of 238U per gram. Estimate the ageof the mineral, assuming that all of the He is retained, andgiven that t1/2 of 238U is 4.47 × 109years.
