Answer:
20.27 mol
Explanation:
454 L x (1 mol/22.4 L) = 20.27 mol
Answer:
60.12 miles
Explanation:
Using the calculation formula shown below:
![t_{1/2} =\frac{t}{[tex]log_{2}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%20%3D%5Cfrac%7Bt%7D%7B%5Btex%5Dlog_%7B2%7D)
\frac{N_{o} }{N_{t} } }[/tex]
where:
is the half life, 
is the original amount of F-18, and 
is the remaining amount of F-18 at time t.
Generally, F-18 has an half life of 1.83 hours.
Therefore:
![t = 1.83*[tex]log_{2}](https://tex.z-dn.net/?f=t%20%3D%201.83%2A%5Btex%5Dlog_%7B2%7D)
\frac{100}{68} = 1.02 hours[/tex]
Therefore using a speed of 59 miles/hour, the closeness of the hospital is:
distance = speed*time = 59*1.02 = 60.12 miles
