A certain substance X has a normal boiling point of 131.9°C and a molal boiling point elevation constant =Kb·1.78°C·kgmol−1. A solution is prepared by dissolving some urea ((NH2)2 CO) in 600.g of X. This solution boils at 133.7°C. Calculate the mass of urea that was dissolved. Round your answer to 2 significant digits.
