A student collected the following data for a fixed volume of gas:Temperature (C)Pressure (mm of Hg)107262075040800708801009601501085Fill in the missing data point. Show all calculations leading to an answer.The General Law of Gases states thatP1*V1/T1 = P2*V2/T2.As Volume is constant, we can write this asP1/T1 = P2/T2,P1 and T1 are the pressure and temperature at time 1.P2 and T2 are the pressure and temperature at time 2.You can take any pair of values as P1 and T1 and find P2 = P1T2/T1, once you sum 273.15 to eachtemperature to get kelvins.P1 = 726 mm HgT1 = 10 + 273.15 = 283.15 K;T2 = 150 + 273.15 = 423.15 K.Then, P2 = 726 * 423.15/283.15 = 1085.96 mm Hg.2. You are given a clear solution of KNO3. Using 3 4 sentences (in your own word ...
