What volume is occupied by 0.118 mol of helium gas at a pressure of 0.97 atm and a temperature of 305 K? Would the volume be different if the gas was argon (under the same conditions)?

검증된 단계별 안내

Identify the ideal gas law equation: PV = nRT.

Determine the values for each variable: P = 0.97 atm, n = 0.118 mol, R = 0.0821 L·atm/(mol·K), T = 305 K.

Rearrange the ideal gas law to solve for volume (V): V = nRT / P.

Substitute the known values into the equation: V = (0.118 mol) * (0.0821 L·atm/(mol·K)) * (305 K) / (0.97 atm).

Calculate the volume for helium. Note that the volume would be the same for argon under the same conditions, as the ideal gas law does not depend on the type of gas.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Ideal Gas Law

The Ideal Gas Law is a fundamental equation in chemistry that relates the pressure, volume, temperature, and number of moles of a gas. It is expressed as PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. This law allows us to calculate the volume occupied by a gas under specific conditions.

Gas Behavior and Properties

Gases behave differently than solids and liquids due to their high kinetic energy and the large distances between particles. This behavior is influenced by factors such as pressure and temperature. Understanding these properties is crucial for predicting how different gases, like helium and argon, will occupy space under the same conditions.

Molar Volume of Gases

The molar volume of a gas is the volume occupied by one mole of the gas at standard temperature and pressure (STP). While the molar volume can vary slightly with different gases due to their molecular weights and interactions, under ideal conditions, the volume occupied by a given number of moles of any ideal gas is the same, regardless of the type of gas.
