Consider the reaction A ==> B. If the reaction is first-order in A with the initial concentration A being 6.048M, what is the concentration of A after 1.986 seconds if the rate constant is 0.483s-1?

Error tolerance: ±0.5%


Can someone explain how to do this? Thanks

ln(Ao/A) = kt
You know Ao, solve for A, you know k and you know t.
