1. A gas occupying a volume of 725 ml at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final vol
2. A 2.10-L vessel contains 4.65 g of a gas at 1.00 atm and 27.0°C. a. Calculate the density of the gas in grams per liter. b. What is the molar mass of the gas?
3. A mixture of gases contains CH CH., and CH. If the total pressure is 1.50 atm and the numbers of moles of the gases present are 0.31 mole for CH., 0.25 mole for CH., and 0.29 mole for CHg, calculate the partial pressures of the gases.
4. State the following gas laws in words and also in the form of an equation: Boyle's law. Charles's law, Avogadro's law. In each case, indicate the conditions under which the law is applicable, and give the units for each quantity in the equation.
