Calculate the volume in ml of he collected at stp when 3.60, Ask an Expert

Academics

Alpha particles produced by radioactive decay evetually pick up electons from their surroundings to form helium atoms. Calculate the volume (in mL) of He collected at STP when 3.60 g of pure 226Ra is stored in a closed container for 135 years. (assume that there are five alpha particles generated per 226Ra as it decays to 206 Pb).
