The boiling point of pure Benzene is 80.1 °C. When 20.97 g of an unknown solid are added to 250.0 mL of Benzene the solution is raised to 83.04°C . Given that the ebullioscopic constant (Kb) is 2.53 °C/molal, what is the molar mass of the unknown solid? (dbenzene = 0.876 g/mL)

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
