QUESTION:
Use the ideal gas law to show that 28.0 g of nitrogen gas and 4.00 g of helium gas occupy the same volume at any temperature and pressure.
ANSWER:
Solution 100P
Step 1:
Here, we are going to show that 28.0 g of nitrogen gas and 4.00 g of helium gas occupy the same volume at any temperature and pressure.
Step 1: Calculation of number of moles.
Molar mass of Nitrogen = 28.0 g/mol
Molar mass of Helium = 4.0 g/mol
Thus, we know
No. of mole for Nitrogen gas , n = Mass/molar mass = m/M
= 28.0 g/28.0g mol-1
= 1.0 mol
Similarly,
No. of mole for Helium gas , n = Mass/molar mass = m/M
= 4 g/4.0 g mol-1
= 1.0 mol
