A mixture of gases has the following partial pressure for the component gases at 20 degrees Celsius: oxygen 180.0 torr, nitrogen 3200 torr, and hydrogen 246.0 torr. Calculate the pressure of the mixture.

Ptotal = pO2 + pH2 + pN2

To calculate the pressure of the mixture, you need to add up the partial pressures of the individual gases.

In this case, you have the partial pressures of three gases: oxygen, nitrogen, and hydrogen.

To calculate the pressure of the mixture, simply add up the partial pressures of the gases:

Pressure of the mixture = Partial pressure of oxygen + Partial pressure of nitrogen + Partial pressure of hydrogen

Pressure of the mixture = 180.0 torr + 3200 torr + 246.0 torr

Pressure of the mixture = 3626.0 torr

Therefore, the pressure of the mixture is 3626.0 torr.
