Draw temperature composition phase diagram for binary System?

Use the following information to draw a temperature-composition phase diagram for the binary system of H₂O (A) and Na₂SO₄ (B) at p = 1 bar, confining t to the range 20 to 50 C and z_B to the range 0-0.2. The solid decahydrate, Na₂SO₄. 10H₂O, is stable below 32.4°C. The anhydrous salt, Na₂SO₄, is stable above this temperature. There is a peritectic point for these two solids and the solution at x_B = 0.059 and t = 32.4°C. There is a eutectic point for ice, Na₂SO₄ .10H₂O, and the solution at x_B = 0.006 and t = 1.3°C.
