Concept explainers
(a)
Interpretation:
The molar mass of the gas needs to be determined.
Concept Introduction:
The ideal gas equation is combination of different
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
The mass of a substance can be calculated from number of moles and molar mass as follows:
Here, n is number of moles and M is molar mass.
(b)
Interpretation:
The molecular formula of the gas needs to be determined.
Concept Introduction:
The ideal gas equation is combination of different gas laws such as Boyle’s law, Charles’s law, Gay-Lussac law etc. The combination of all these laws gives the ideal gas equation.
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
The mass of a substance can be calculated from number of moles and molar mass as follows:
Here, n is number of moles and M is molar mass.
