Suppose a laboratory has a 38 g sample of polonium-210. the half-life of polonium-210 is about 138 days. how many half-lives of polonium-210 occur in 1104 days? how much polonium is in the sample 1104 days later? 9 ; 0.07 g 8 ; 2,2622 g 8 ; 4.75 g 8 ; 0.15 g

D. 8; 0.15 g

Step-by-step explanation:

We have been given that a a laboratory has a 38 g sample of polonium-210. The half-life of polonium-210 is about 138 days.

To find the half-lives of polonium-210, we will divide 1104 by 138.

Therefore, there are 8 half-lives will occur in 1104 days.

Therefore, 0.15 gm of the polonium will be left after 1104 days.
