Topic: Practice exercise on gas laws. You must write the equation you are using to solve the exercise. 1. A sample of Argon gas occupies an initial volume of 5.40 L when its pressure is 6.52 atm. What will be the final pressure of the gas if its volume increases to 9.73 L? 2. An unknown gas occupies an initial volume of 0.256 L when its temperature equals 121ºC. What will be the final volume if the temperature drops to...
