Answer : The initial concentration of A is, 0.347 mol/L
Explanation :
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = 
t = time passed by the sample = 5 s
a = initial amount of the reactant = ?
a - x = amount left after decay process = 0.081 mol/L
Now put all the given values in above equation, we get


Therefore, the initial concentration of A is, 0.347 mol/L
