Answer:

Explanation:
We are asked to find how much of a 40 gram sample remains after 12 years. 
Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed. 
- 12 years/3 years = 4 half-lives
Every time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample. 
- 1 half- life: 40 g / 2 = 20 g 
- 2 half-lives: 20 g / 2= 10 g 
- 3 half-lives: 10 g / 2 = 5 g
- 4 half-lives: 5 g / 2 = 2.5 g
There is also a formula that can be used to solve this problem. 

Where A₀ is the initial amount, t is the time, and hl is the half-life. 
We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife. 




After 12 years, <u>2.5 grams </u> of Iron-55 will remain. 
 
        
             
        
        
        
Answer:
125 molecules
Explanation:
Between two amino acids , one water molecule is eliminated and a peptide bond is formed. When 250 amino acids are joined to form a polypeptide , 125 molecules of water will be removed.
That is, 250/2=125
