**Steve**, Monday, January 7, 2013 at 3:16pm1104/138 = 8 half-lives

after 8 half-lives, 1/256 remains, or 0.148g

**drwls**, Monday, January 7, 2013 at 3:18pmHow many half-lives of polonium-210 occur in 1104 days? 1104/138 = 8.0 half-lives

How much polonium is in the sample 1104 days later? 38 g * (1/2)^8 = 0.148 g
