Describe how you would prepare each of the following aqueous solutions:
(a) 1.50 L of 0.110 M (NH4)2SO4 solution, starting with solid (NH4)2SO4;
(b) 225 g of a solution that is 0.65 m in Na2CO3, starting with the solid solute;
(c) 1.20 L of a solution that is Pb(NO3)2 by mass (the density of the solution is 1.16 g/mL), starting with solid solute;
(d) a 0.50 M solution of HCl that would just neutralize 5.5 g of Ba(OH)2 starting with 6.0 M HCl?
