<u>Answer: </u>The mass of sample that remained is 0.127 mg
<u>Explanation:</u>
The integrated rate law equation for first-order kinetics:
......(1)
Given values:
a = initial concentration of reactant = 0.500 mg
a - x = concentration of reactant left after time 't' = ?mg
t = time period = 28 s
k = rate constant =
Putting values in equation 1:
Hence, the mass of sample that remained is 0.127 mg
