If a 0.610 m aqueous solution freezes at –3.00 °c, what is the van\'t hoff factor, i, of the solute? kf values can be found here.

ΔT = 3°C = 3 K.
Kf(H₂O) = 1,853 K·kg/mol.
b = 0,610 m = 0,610 mol/kg.
b = n ÷ m(H₂O).
ΔT = Kf · b · i.
i = ΔT / Kf · b.
i = 3 K / 1,853 K·kg/mol · 0,610 mol/kg.
i = 2,65.
i - Van 't Hoff factor.
b - molality.
ΔT - change in temperature.

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.
