= Radium-226 (atomic mass = 226.03), the only naturally occurring isotope of this element, follows the decay sequence shown below. a (3.10 min) 214 Pb a (3.82 day) 218 Po a (1602 yr) 222 Rn 226 Ra Each step occurs by alpha emission. The half-life for each step is shown below the arrow. How many years would it take for a 1.56 g sample of 226Ra to produce 13.34 mL of helium measured g at 27 °C and 674 torr following this decay sequence?
