Gas Laws Worksheet: Key Concepts and Applications

Gas Laws Worksheet Name__________________________ Period____________ If 400 cm 3 of oxygen is collected at a pressure of 980 mmHg, what volume will the gas occupy if the pressure were changed to 940 mmHg? What is the volume of hydrogen at a pressure of 1.06 atm if 200 cm 3 of hydrogen is collected at a pressure of 1.00 atm? The pressure on 2.50 L on anesthetic gas changes from 760 mmHg to 304 mmHg. What will be the new volume if the temperature remains constant? A gas sample occupies 200 mL at 760 mmHg. What volume does the gas occupy at 400 mmHg? Nitrogen gas in a steel cylinder is under pressure of 150 atm at 27°C. What will the pressure in the tank be if the tank is left in the sun and the internal temperature rises to 55°C? If a sample of a gas occupies 6.8 L at 327°C, what will be its volume at 27°C if the pressure does not change? A gas occupies a volume of 560 cm 3 at a temperature of 100°C. To what temperature must the gas be lowered to if it is to occupy 400 cm 3 ? Assume constant pressure. What is the volume of a gas at -20°C if the gas occupied 50.0 cm 3 at a temperature of 0°C? What pressure will be exerted by 0.450 moles of a gas at 25°C if it is contained in a vessel whose volume is 650 cm 3 ? Determine the volume occupied by 0.582 moles of a gas at 15°C if the pressure is 622 mmHg. What is the temperature of the gas inside a 750 mL balloon filled with 0.015 moles of H 2 gas if the pressure of the balloon is 1.2 atm. From the volume, temperature, and pressure calculate the number of moles and the mass in grams for the gas listed below.
