Answer:
800 g
Explanation:
We can express the decay of I-37 using the formula:
- Final Mass = Initial Mass * [tex]0.5^{\frac{Time}{Half-Life} }[/tex]
We input the data:
- 25 g = Initial Mass * [tex]0.5^{(\frac{40.35}{8.07})}[/tex]
And solve for Initial Mass:
- 25 g = Initial Mass * [tex]0.5^{5}[/tex]
- 25 g = Initial Mass * 0.03125
Meaning that out 800 grams of I-37, only 25 will remain after 40.35 days.
