Final temperature after urea dissolves in water
Urea, (NH2)2 (CO), is used in the manufacture of resins and glues. When 5.00 g of urea is dissolved in 250.0 mL of water (d=1.00 g/mL) at 30.0°C, 27.6 kJ of heat is absorbed. What is the final temperature of the solution in kJ? The density of water is 4.18 J/g·°C. What is the final temperature in °F? F = °C x 1.8 + 32 (Round your answer to one decimal place)
