1.1 moles of C10H8 is the limiting reagent in the reaction between reaction C10H8 and O2
.
C10H8 + 12O2 ----> 10CO2 + 4H2O
C10H8 is the limiting reagent since 1.1 moles of C10H8 is totally consumed during the reaction
For this problem, we use the formula for
radioactive decay which is expressed as follows:<span>
An = Aoe^-kt
where An is the amount left after time t, Ao is
the initial amount and k is a constant.
We calculate as follows:
An = Aoe^-kt
0.5 = e^-k(4.5)
k = 0.1540
An = Aoe^-kt
An = 16e^-0.1540(18)
<span>An = 1.00 mg</span></span>
Hope this answers the question. Have a nice day.
