Problem #1: A gas has a volume of 800.0 mL at −23.0 °C and 300.0 torr. What would the volume of the gas be at 227.0 °C and 600.0 torr of pressure? Solution: 1) Set up all the problem values in a solution matrix: 2) The combined gas law is rearranged to isolate V 2: 3) Values are inserted into the proper places: V 2 = 800.0 mL.

Chemistry: The Combined Gas Law. KEY. Solve the following problems. As always, include enough work and show the units to ensure full credit. 1. The pressure of a gas changes from 120 kPa to 50 kPa. The volume changes from 45 L to 40 L. If the initial temperature is 81oC, what is the final temperature in oC? P 1 120 kPa. 45 L. T 81 o C 273.
Combined Gas Law Worksheet - Solutions. 1) If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm? (1.1 atm)(4.0 L) = (3.4 atm)(x L) x = 1.29 L. 2) A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L.
Use the combined gas law to solve the following problems: 1) If I initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas? 2) A gas takes up a volume of 17 liters, has a pressure of 2.3 atm ...
Mixed Gas Laws Worksheet. 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 250 C, what will the pressure of the resulting mixture of gases be?
Combined Gas Law Problems: atm = 760.0 mm Hg = 101.3 kPa= 760 .0 torr. 9. A gas balloon has a volume of 106.0 liters when the temperature is 45.0 °C and the pressure is 740.0 mm of mercury.
Combined Gas Law Worksheet - Solutions 1) If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm? (1.1 atm)(4.0 L) = (3.4 atm)( x L) x = 1.29 L 2) A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L.
