Understand that diluting a solution by three orders of magnitude means the concentration decreases by a factor of 10^3 (which is 1000).
Write the initial concentration as \(C_1 = 0.1\,M\) and the dilution factor as \(10^3 = 1000\).
Use the dilution relationship: \(C_2 = \frac{C_1}{\text{dilution factor}}\) where \(C_2\) is the new concentration after dilution.
Substitute the values into the formula: \(C_2 = \frac{0.1}{1000}\).
Simplify the expression to find the new concentration, which will be \(0.0001\,M\).
