Beer Lambert problem, where did I go wrong?

Homework Statement

Light intensity decreases by a factor of 100 when light passes through a 1cm cuvette with solution. Molar extinction coefficient is 105M-1cm-1. Find concentration.

Relevant Equations

A=ECL
A = log(io/I)

A=ECL
A = log(io/I)
A = log100/1 = 2

2/105M(1cm) = 0.019M ~ 20mM

Apparently the answer is 2mM, where did I go wrong?

Your answer looks right to me, assuming you have copied the question correctly.
