An aqueous solution is prepared by dissolving 0.415g of KMnO4 in 250.0mL of water. This solution is then diluted by taking a 25.0mL aliquot (sample) and diluting it to 100.0mL with water. A third solution is then prepared by taking 10.0mL of the diluted solution and further diluting it to 50.0mL with water. Show how to determine (and then calculate) the molarity of each solution (the 3 different solutions prepared). Use the factor-label (Conversion-factor) method for all conversions. Be sure to include units where applicable. All numeric answers must be round to significant figures.
