A student investigated the stoichiometry of the reaction of zinc (Zn) with HCI solution and reported the following data: When 0.2158 g of Zn reacted with 10.00 mL of 1.000M HCI, 82.062 g of water was displaced. A total of 36.00 mL of 9.501 x 102M NaOH solution was required to titrate the HCI remaining in the reaction mixture at the end of the reaction. The room temperature was 27.0°C and the barometric pressure was 777 torr. The gram atomic mass of Zn is 65.38 g mol1. The density of water at 27.0 °C is 0.9965 g mL and its vapor pressure is 27.0 torr. R = 8.21 X.10 2 L- atm K1 mol 1 !! Calculate the number of millimoles of HCI remaining in the flask at the end of the reaction
