Interpretation: To determine the number of moles of a contained gas when pressure, volume, and temperature are known.
Concept Introduction: The International System of Units uses the mole (symbol, mol) as the unit of material quantity. However many elementary entities of a particular substance present in an object or sample are determined by the quantity of that material.
Answer to Problem 30LC
The number of moles can be determined by using the ideal gas equation which is
Explanation of Solution
The number of moles can be determined by using the ideal gas equation:
Here, P is pressure, V is volume, R is gas constant and T is temperature.
By rearranging equation (i).
By using equation (ii), the number of moles of gas can be determined.
