Sample Problem: A water sample was tested for iron content, but was diluted prior to obtaining the instrument reading. This dilution involved taking 10.00 mL of the sample and diluting it to 100.00 mL. If the instrument reading gave a concentration of o.891 ppm for this diluted sample, what is the concentration in the undiluted sample? O Approach A: Compute for the weight of solute and then the concentration O Approach B: use the dilution factor (dilution Yolume/sample yolume)
