Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Question

**Problem Statement:**

If a gaseous mixture is made by combining 3.07 g of Ar and 2.59 g of Kr in an evacuated 2.50 L container at 25.0 °C, what are the partial pressures of each gas, \( P_{\text{Ar}} \) and \( P_{\text{Kr}} \), and what is the total pressure, \( P_{\text{total}} \), exerted by the gaseous mixture?

**Variables to Determine:**

- \( P_{\text{Ar}} \) = ____ atm
- \( P_{\text{Kr}} \) = ____ atm
- \( P_{\text{total}} \) = ____ atm

**Instructions:**

1. Calculate the number of moles of Ar and Kr using their respective molar masses.
2. Use the ideal gas law \( PV = nRT \) to find the partial pressures of Ar and Kr, where:
- \( P \) is pressure,
- \( V \) is volume (2.50 L),
- \( n \) is the number of moles,
- \( R \) is the ideal gas constant (0.0821 L·atm/mol·K),
- \( T \) is temperature in Kelvin (25.0 °C + 273.15).

3. Add the partial pressures to find the total pressure.
