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
Answer:
1. Mole fraction of Ne is 2/7
2. The partial pressure of Ne is 1.43 atm
Explanation:
Step 1:
Data obtained from the question. This includes:
Mole of He = 4 moles
Mole of Ne = 2 moles
Mole of Ar = 1 mole
Total mole = 7 moles
Total pressure = 5 atm
Step 2:
Determination of the mole fraction of Ne.
Mole fraction of a gas is simply the ratio of the mole of the gas to the total mole of the gas present.
Mole fraction of Ne = mol of Ne/ total mole
Mole fraction of Ne = 2/7
Step 3:
Determination of the partial pressure of Ne.
Partial pressure = mole fraction x total pressure
Partial pressure of Ne = 2/7 x 5
Partial pressure of Ne = 1.43 atm
