3.00 g of potassium hydroxide (KOH) pellets are put into a constant-pressure calorimeter containing 250 mL of water. The initial temperature of the water is 22.3°C. The mixture is then stirred until all of the KOH is dissolved. The final temperature of the solution is measured and recorded as 29.7°C. Calculate the heat of solution for potassium hydroxide (ΔH_soln). The specific heat capacity of the solution may be assumed to be the same as that of water since this is a dilute solution. Assume no heat loss from the calorimeter.

What mass of KOH do you need to dissolve to reach a final temperature of 38 °C?
