What is the shape of the binary liquid -vapour phase diagram for acetone and chloroform?Does it show a positive or negative deviation from  Raoult's law

Solid-liquid phase diagram of naphthalene-biphenyl system was formed by determination of arrest and break points in cooling curves of different composition mixtures as follows 82 283 2222 90 80 Temperature (°C) 111 70 1 50 40 30 20 10 0 Area Area 1 0.2 Phase Diagram Area Il Area IV Area III 0.8 0.4 0.6 Mole fraction of naphthalene 1 a. Write the phases of naphthalene and biphenyl in different areas on graph (assume that these molecules are completely miscible in liquid phase and immiscible in solid phase) of phases Explanations (Which phases present?) 12 b. Explain briefly the eutectic point and explain its position on graph

In this lab, you will start off by calculating the number of moles of air molecules inside a flask containing 20 mL of water by cooling the flask down to near 0°C and assuming the vapour pressure of water is negligible at that temperature. If the volume of the air inside the flask is 145.2 mL, the gas pressure sensors reads 101.3 kPa and the temperature sensor reads 3.7 °C, how many moles of air are present in the flask? Express your answer in mol. Assume R = 8.314 J mol-¹ K-¹. Answer:
