A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 atm and 4.34 atm, respectively.

What is the total pressure of the tank?
atm = pressure

A. 2.50 atm
B. 2.73 atm
C. 5.95 atm
D. 6.90 atm

The total pressure of the tank is the sum of the partial pressures of nitrogen and oxygen. Therefore, the total pressure is:

1.61 atm + 4.34 atm = 5.95 atm

Therefore, the total pressure of the tank is 5.95 atm.

C. 5.95 atm
