Concept explainers
(a)
Interpretation:
The number of moles of Ar gas at STP and 4.0 L volume needs to be determined.
Concept Introduction:
The ideal gas equation is represented as follows:
Here, n is number of moles, P is pressure, V is volume, R is Universal gas constant and T is temperature.
In the STP condition the volume occupied by one mole gas = 22.4L
The conversion factor
(b)
Interpretation:
The number of moles of Ar gas at STP and 31.2 L volume needs to be determined.
Concept Introduction:
The ideal gas equation is represented as follows:
Here, n is number of moles, P is pressure, V is volume, R is Universal gas constant and T is temperature.
In the STP condition the volume occupied by one mole gas = 22.4L
The conversion factor
(c)
Interpretation:
The number of moles of Ar gas at STP and 120.0 mL volume needs to be determined.
Concept Introduction:
The ideal gas equation is represented as follows:
