Problem
A reactant A is converted to product D according to 2A(aq)→3D(aq). The concentration of A decreases from 0.300 M to 0.215 M in 120 s. Each concentration of A is measured with an absolute uncertainty of ±0.004 M.
(a) Calculate the concentration of D produced after 120 s.
(b) Determine the absolute uncertainty in the concentration of D you calculated in part (a).
