Answer:
6.25 mg
Explanation:
32 days equals 4 half lives for the iodine, since one half life is 8 days. So, the first half life goes from 100 to 50 mg, second from 50 to 25, third from 25 to 12.5, and fourth from 12.5 to 6.25
I cannot answer this question exactly if the choices are not given. There is obviously more to this question. However, I can still give an idea about the vapor pressure of water and acetone. Acetone is a liquid ketone. It is more volatile compared to water. Therefore, you will expect acetone to have a lower vapor pressure than water. With the same conditions and same amount of initial volume, at a certain amount of time, the amount of liquid left in the container for water than acetone. This is because most of the acetone has already vaporized.
W*V i believe because it comes down to this :
I is the current, W is wattage V is volts and the * is the thing that represents the Amperes (i’m not 100% but this is my best)
