Ideal Gas Equation

From ideal gas equation, For The molar volume of at a)NTP b) and c) and d) and Therefore the molar volume of is maximum at and .

Step 1: Total moles:
Step 2: Let masses be (H ) and (He):
Step 3: Given:
Step 4: Solving gives:

The average kinetic energy of an ideal gas per molecule in SI units at will be The average kinetic energy of an ideal gas per molecule is given by the expression Average kinetic energy Here, is boltzmann constant and is absolute temperature. Average kinetic energy

Step 1: By Avogadro’s law, equal volumes of gases at same T and P contain equal number of molecules.

Step 1: Let masses be mH and mHe.
Step 2: Using ideal gas law and molar masses: (mH)/(2) + fracmHe4 = constant
Step 3: Using total mass mH + mHe = 5, solving gives: mH : mHe = 2 : 3

Step 1: Understanding the Concept:
We first need to determine the volume of the vessel using the mass and density of the liquid. Once the volume is known, we can use the Ideal Gas Equation to find the molar mass of the gas.

Step 2: Key Formula or Approach:
1. Volume of vessel ( ) =
2. Ideal Gas Law: , where is the molar mass.

Step 3: Detailed Explanation:
1. Find the volume of the vessel: 2. Find the mass of the gas: 3. Calculate Molar Mass ( ): Rearranging : Substitute the values: , , , , . Notice that :

Step 4: Final Answer
The molar mass of the gas is 125 g mol .
