One beaker contains 25 mL of 1.60 M HCl, and a second beaker contains 60 mL of 0.40 M NaOH. Both solutions were initially at 20 C. We pour both beakers into a large insulated container which contains 10 g of ice, initially at -60 C. Calculate the final temperature of the resulting solution. Note that the heat of neutralization is -57.3 kJ/mol.
