Question
1) How many moles of gas occupy 98 L at a pressure of 2.8 atmospheres and a temperature of 292 K? 2) If 5.0 moles of O2 and 3.0 moles of N2 are placed in a 30.0 L tank at a temperature of 25° C, what will the pressure of the resulting mixture of gases be? 3) A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. How many moles of gas does the tank contain? 4) A balloon that can hold 85 L of air is inflated with 3.5 moles of gas at a pressure of 1.0 atmosphere. What is the temperature in °C of the balloon? 5) CaCO3 decomposes at 1200° C to form CO2 gas and Cao. If 25 L of CO, are collected at 1200° C, what will the volume of this gas be after it cools to 25º C? of 2
