When 5.19 mg of a pure unknown compound is mixed with 46.29 mg of camphor,* the observed freezing point of the resulting mixture is 158.1. °C. Camphor's freezing
point is: 179.8 °C.
What is the molecular weight (g/mol) of the unknown?
Camphor's Kf is listed in the table above. You may use the table to help guide you
through the calculation.

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.
