Final answer:
Using Dalton's law of partial pressures and the mole fraction, the partial pressure of Ne in a 0.95 atm gas mixture containing 0.32 mol He and 0.56 mol Ne is calculated to be 0.6068 atm.
Step-by-step explanation:
The subject of this question is Chemistry, specifically the concept of Dalton's law of partial pressures and gas laws. The student is inquiring about the partial pressure of neon (Ne) in a mixture of gases which also contains helium (He) and has been given the total pressure of the mixture.
To find the partial pressure of Ne, we can use Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas. Since the total pressure and the moles of each gas are known, we can calculate the partial pressures.
The calculation is as follows:
- Total moles of gas = moles of He + moles of Ne = 0.32 mol + 0.56 mol = 0.88 mol
- Partial pressure of Ne = (moles of Ne / total moles of gas) * total pressure = (0.56 mol / 0.88 mol) * 0.95 atm
- Partial pressure of Ne = 0.6068 atm
Therefore, the partial pressure of Ne in the mixture is 0.6068 atm.
