Chemistry

3.00 g of potassium hydroxide (KOH) pellets are put into aconstant-pressure calorimeter containing 250 mL of water. Theinitial temperature of the water is 22.3°C. The mixture is thenstirred until all of the KOH is dissolved. The final temperature ofthe solution is measured and recorded as 29.7°C. Calculatethe heat of solution for potassium hydroxide(ΔHsoln). The specific heat capacity of thesolution may be assumed to be the same as that of water since thisis a dilute solution. Assume no heat loss from the calorimeter.

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