28 Μαΐ 2020 · A sample of gas isolated from unrefined petroleum contains 90.0% CH 4, 8.9% C 2 H 6, and 1.1% C 3 H 8 at a total pressure of 307.2 kPa. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.) Answer.
8 Φεβ 2022 · This ideal gas law example problem shows the steps needed to use the Ideal Gas Law equation to determine the amount of gas in a system when the pressure, volume, and temperature are known. Problem. A cylinder of argon gas contains 50.0 L of Ar at 18.4 atm and 127 °C. How many moles of argon is in the cylinder? Solution
Using the Ideal Gas Equation in Changing or Constant Environmental Conditions. 1) If you were to take a volleyball scuba diving with you what would be its new volume if it started at the surface with a volume of 2.00L, under a pressure of 752.0 mmHg and a temperature of 20.0°C?
23 Απρ 2019 · Problem (4) on The ideal gas law. Calculate the volume of 42.6 g of oxygen gas at 35 o C and 792 torr. Solution – Because the value of R given previously has units of liters, atmospheres, moles, and kelvins, the data given here are converted to these units:

Exercises. Exercise 1. Derive the value of the gas constant, R, where the pressure is in torr and volume is in mL. The ideal gas law is PV = nRT. Solve for R. R = PV nT. At STP: P = 760 mmHg, V = 22410. mL, n = 1 mole, T = 273.15 K. R = PV nT = 760 mmHg × 22410 mL 1 mol × 273.15 K = 6.24 × 104 mmHg ⋅ mL mol ⋅ K.
