Answer:
768g
Explanation:
We can use to formula 
. Here, N(A) is the final amount. N0 is the initial amount. t is the time elapsed, and 
is the half life. Plugging in, we get the answer above.
The answers D) -60
Just subtract
PV = nRTP is pressure, V is volume in L, n is number of moles, R is the gas constant,and T is temperature in K
(1.5 atm)(1 L) = (n)(.08206)(301K)
n = .06 moles in one liter
If there are 3.9 grams in .06 moles then
1/.06 x 3.9 = 64.2 grams per mol
