diagram should be correct and clear

3. Draw a phase diagram (temperature vs. composition) using the following information. Melting point of pure compound A: 50C; melting point of pure compound B:90C; eutectic temperature 20C; molar A/B ratio at eutectic point: 1:2 mol/mol. Assume linear behavior between these points. Mark and describe all phases. What phase(s) exist at a temperature of 30C in a mixture of A and B containing 30%B ? (10p)
