## Practice Questions

 1 Calculate the molarity of a solution prepared by adding 45.2 g of solid NaOH to 250 mL of water. 2 Calculate the number of grams of NaOH needed to make a 350 mL solution of a 3.0 M NaOH solution.
 3 Calculate the normality of a solution of 0.56 moles of ethanol in 250 g of water. 4 How many moles of ethanol are needed to make a 1.2 kg, 2.1 m solution?
 5 Calculate the normality of a solution of 2.56 moles of H2SO4 in 250 mL of water. 6 How many moles of H3PO4 is needed to make 250 mL of 2.5 N H3PO4(aq)?
 7 How much 15.0 M HNO3 is needed to make 1.5 liters of 1.0 M HNO3? 8 Calculate the molarity of a solution prepared by combining 450 mL of water with 20 mL of concentrated HCl (12 M). 9 How much 19.2 M NaOH is needed to make 1.5 liters of 1.0 M NaOH?
 10 Exactly 25.46 mL of 0.125 M NaOH was titrated to the equivalence point with 25.0 mL of an unknown concentration of HCl. Calculate the molarity of the HCl solution. 11 What volume of 2.00 M HNO3 will react completely with 25.0 mL of 6.00 M NaOH? 12 What volume of 6.00 M KOH will react completely with 25.0 mL of 6.00 M H2SO4? (Hint: The sulfuric acid has two protons that can react with the KOH.)

 1 4.5 M 2 42.0 g 3 2.2 M 4 2.5 moles 5 20.5 N 6 0.21 moles 7 0.10 L 8 0.51 M 9 0.078 L = 78 mL 10 0.127 M 11 75.0 mL 12 50.0 mL
