Calculate the freezing point and boiling point of a 0.100m aqueous solution of K2SO4.
a) Freezing point = -1.86°C; Boiling point = 100.512°C
b) Freezing point = -0.186°C; Boiling point = 101.512°C
c) Freezing point = -1.86°C; Boiling point = 100.012°C
d) Freezing point = -0.186°C; Boiling point = 100.512°C"
