Using data from this table of molal boiling-point-elevation and freezing-point-depression constants, calculate the freezing and boiling points of each of the following solutions.
a)0.39 m glucose in ethanol
(b) 22.8 g of decane, C10H22, in 53.9 g CHCl3
(c) 3.90 g NaOH in 109 g of water
(d) 0.37 mol ethylene glycol and 0.27 mol KBr in 194 g H2O
how do i do these?
