Physical Chemistry question:

a) By using the info in the table draw a phase diagram for the A-B system ( each value in the table shows the gram value fo B inside a 50 g solution. All the values given correspond to the concentrations on the phase line)

b) In a system containing 65g water and 35 g phenol find the amount of both phases in 310K and find the weight percentage in terms of B in grams

c) When a liquid system of 85 C that contains 60 g B and 40 g A is cooled down, at which temperature can one observe two phases for the first time? Determine the amount of both phases in terms of phenol in grams
