Interpretation:
The partial pressures of helium and neon are to be calculated with given volume, pressure, and temperature.
Concept Introduction:
The ideal gas equation elaborates the physical properties of gases by relating the pressure, volume, temperature, and number of moles with each other with the help of four
Here,
The expression to calculate mole fraction
Here,
The relation between partial pressure
The conversion of temperature from degree Celsius to Kelvin can be done by using the formula given below:
