(a)
Interpretation:
The number of moles of
Concept Introduction:
According to
For comparison, STP conditions are taken under consideration that is standard temperature and standard pressure.
Standard Temperature = 0°C (273 K)
Standard Pressure = 1 atm (760 mmHg)
At STP, one mole of any gas occupies a volume of 22.4 L and this volume of any gas is known as molar volume.
(b)
Interpretation:
The volume in liters occupied by 2.50 mol of N2 gas should be calculated by using molar volume.
