2. How many moles of H. SO, are present in 0.500 L of a 0.150 M H SO,
solution?
3. What volume of 3.00 M NaCl is needed for a reaction that requires
146.3 g of NaCI?

65.0 mL of a 2.20 M solution of NaOH in H2O?
(Hint: See Sample Problem 13-2.)
18. A solution is made by dissolving 26.42 g of
(NH4)2SO4 in enough H2O to make 50.00 mL
of solution.
