Answer:
The partial pressure of N2O is 143.6 kPa
Explanation:
Step 1: Data given
Moles O2 = 2.83 mol
Moles N2O = 8.41 mol
Total pressure = 192 kPa
Step 2: Calculate total number of moles
Total numberof moles = moles O2 + molesN2O = 2.83 + 8.41 = 11.24 mol
Step 3: Calculate mole fraction of N2O
Mole fraction N2O = mole N2O / Total moles
Mole fraction N2O = 8.41 / 11.24 = 0.748
Step 4: Calculate partial pressure of N2O
pN2O = 0.748 * 192 kPa
pN2O = 143.6 kPa
The partial pressure of N2O is 143.6 kPa
Answer: 144 kPa
Explanation:
To determine the partial pressure of N2O, first determine the mole fraction of N2O in the mixture, then multiply the mole fraction of N2O by the total pressure.
XN2O = nN2O/ ntotal = 8.41 mol / 2.83 mol + 8.41 mol = 0.7482
PN2O=XN2O×Ptotal = 0.7482 × 192 kPa = 143.7 kPa
Rounding the answer to three significant figures, the partial pressure of N2O is 144kPa.
