Question
The partial pressures of the gases in a mixture are 0.00461 atm O2, 1.78 atm N2, and 0.975 atm Ar. What is the total pressure of the mixture?A.1.78 atmB.0.800 atmC.4.54 atmD.2.76 atmSUBMITarrow_backPREVIOUS
Solution
Para encontrar la presión total de la mezcla de gases, se deben sumar las presiones parciales de cada gas.
Las presiones parciales son:
- O2: 0.00461 atm
- N2: 1.78 atm
- Ar: 0.975 atm
Sumamos estas presiones parciales:
0.00461 atm + 1.78 atm + 0.975 atm = 2.75961 atm
Redondeando a dos decimales, la presión total es aproximadamente 2.76 atm.
Por lo tanto, la respuesta correcta es:
D. 2.76 atm
