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)

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
