Show the given, formula and solution with units. Box you final answer, expressed in two decimals.
Question 1: Given a 4.00 L of a gas is at 750.0 mm Hg pressure. What is its volume (in mL) at standard pressure?
Question 2: A cylinder contains a gas which has a pressure of 155 kPa at a temperature of 200. K. Find the temperature of the gas (in K) which has a pressure of 1.5 atm if the volume remains constant.
Question 3: Solve the volume of a gas at 32°C if at 18°C the gas occupied a volume of 152 mL.
Question 4: Calculate the mass (in kg) of 25,000 mL of NH 3 at 47 oC and 900 mm Hg.
Question 5: A gas that has a volume of 28 liters, a temperature of 45 C, and an unknown pressure has its volume increased to 34,000 mL liters and its temperature decreased by 35 oC. If I measure the pressure after the change to be 2.0 atm, what was the original pressure of the gas in atm?
