A mixture of 6.00 g O2(g) and 9.00 g CH4(g) is placed in a 15.0-L vessel at 0°C. What is the partial pressure of each gas, and what is the total pressure in the vessel?
A) PO2 = 0.281 atm; PCH4 = 0.841 atm; PT = 1.122 atm
B) PO2 = 0.281 atm; PCH4 = 0.841 atm; PT = 1.12 atm
C) PO2 = 0.281 atm; PCH4 = 0.80 atm; PT = 1.122 atm
D) PO2 = 0.290 atm; PCH4 = 0.841 atm; PT = 1.122 atm
