The following procedure provides a crude method of determining the molar mass of a volatile liquid. A liquid of mass 0.0153 g is introduced into a syringe and the end is capped (sealed). The syringe is transferred to a temperature bath maintained at 58.5 oC, and the liquid vaporizes. As the liquid vaporizes the plunger is pushed out. At equilibrium, the plunger reads 5.76 mL of gas. Atmospheric pressure is 740. mmHg. What is the approximate molar mass of the compound (in g/mol)?

1. A piece of metal "X" weighing 0.0382 g was placed in an eudiometer containing dilute aqueous HCI. After the metal fully dissolved,15.4 mL of hydrogen gas was collected by displacement of water and a 400 mm column of water was observed. The water temperature was 25 degrees Celcius and the barometric pressure was 758.8 mm Hg (torr). Refer to the introduction and data sheet to solve the following problems. a) Calculate the volume occupied by the hydrogen gas at STP. b) How many moles of the metal were consumed in the reaction? c) What is the molar mass of the metal?
