Answer:
Partial pressure of Ne = 1.43 atm
Explanation:
Step 1: Data given
Volume = 3.0 L
Number of moles He = 4 moles
Number of moles Ne = 2 moles
Number of moles Ar = 1 mol
Total pressure = 5 atm
Step 2: Calculate total moles
Total moles = 4 moles + 2 moles + 1 mol
Total moles = 7 moles
Step 3: Calculate the mol ratio
Mol ratio = moles / total mol
Mol ratio He = 4 moles / 7 moles = 0.571
Mol ratio Ne = 2 moles / 7 moles = 0.286
Mol ratio Ar = 1 mol / 7 moles = 0.143 moles
Ste p4: Calculate partial pressure
PArtial pressure = mol ratio * total pressure
Partial pressure of Ne = mol ratio Ne * total pressure
Partial pressure of Ne = 0.286 * 5 atm
Partial pressure of Ne = 1.43 atm
