A tank is being filled through a valve by an ideal gas where the following applies: H=30*T(K) in J/mol for gas, R=8.314 in J/mol/K, H=40 T(K) for the liquid in J/mol (gas as liquid, different reference point than gas)
In the first trial of Part A of the procedure, the ratio of moles H20/moles CaSO4 is found to be 1.93. In the second trial the ratio was found to be 1.98. Calculate the relative average deviation of the two trials. Should the student run another t..
