Answer:
d) 1.25 g
Step-by-step explanation:
If it has a half life of 40 days, there will be 5 half-lives in that span of time so if you divide 40 by 2, 5 times or just [tex]\frac{40}{2^{5} }[/tex], it will equal 1.25.
[tex]\frac{40}{2}=20\\[/tex]
[tex]\frac{20}{2} =10[/tex]
[tex]\frac{10}{2} =5[/tex]
[tex]\frac{5}{2} =2.5\\[/tex]
[tex]\frac{2.5}{2} =1.25[/tex]
