6. [] You have collected a tissue specimen that you would like to preserve by freeze drying (Dr. Cahill does this!!) To ensure the integrity of the specimen, the temperature should not exceed -5.00°C. The vapour pressure of ice at 273.16 K is 624 Pa. What is the maximum pressure at which the freeze drying can be carried out? AH fuzion=6010 J mol-¹ and 4Hvaporization=40656 J mol-¹

Please solve this questionnnnnn correctly, question please, please UR solution
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:
Estimate the melting point of ice under a pressure of 54 bar. Assume that the mass density of ice under these conditions is approximately 0.92 g-cm-3 and that of liquid water is 1.00 g-cm-3
