A student wishes to prepare 2.00 L of 0.100 M KIO3, which has a molecular weight of 214g/mol.  The proper procedure is to weigh out… 42.8 g of KIO3 and add 2.00 kg of H2O 42.8 g of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 L. 21.4 g of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 liters 42.8 grams of KIO3 and add 2.00 liters of H2O 21.4 grams fo KIO3 and add 2.00 liters of H2O

Say you have 2.50 M Caso, solution and you need 300. mL of 0.400 M CaSO, How can you prepare this dilution? * Take 32 mL of a 2.50 M solution and pour into a flask. Add water until total volume equals 200 ml. Take 48 mL of a 2.50 M solution and pour into a flask. Add water until total volume equals 300 ml. Take 1875 mL of a 2.50 M solution and pour into a flask. Add water until total volume equals 300 ml. Take 120 mL of a 2.50 M solution and pour into a flask. Add water until total volume equals 300 ml. How would you prepare 275 mL of 0.600 M KPO, solution? * Twould add 35.0 g K.PO, to enough water to make 275 ml of solution
