6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>
The decay equation for the 13 grams of iron-52 is:
![N(t) = 13g*e^{(-ln(2)/8.3h)*t}}](https://tex.z-dn.net/?f=N%28t%29%20%3D%2013g%2Ae%5E%7B%28-ln%282%29%2F8.3h%29%2At%7D%7D)
Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:
![N(8h) = 13g*e^{(-ln(2)/8.3h)*8h}} = 6.665g](https://tex.z-dn.net/?f=N%288h%29%20%3D%2013g%2Ae%5E%7B%28-ln%282%29%2F8.3h%29%2A8h%7D%7D%20%3D%206.665g)
So 6.665 grams of the 13 grams remain after 8 hours.

Answer:
Around 25 pages / 1.5 minute(s)
Step-by-step explanation:
18 / 12 = 1.5 minutes per paper.
So, 18 + 18 = 36 + 1 = 37 minutes
12 + 12 = 24 + 1 = 25
37 / 25 = 1.5
