Five gases combined in a gas cylinder have the following partial pressures: 3. 00 atm (N2), 1. 80 atm (O2), 0. 29 atm (Ar), 0. 1

Helen [10]

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.

The partial pressure has been defined as the pressure exerted by each gas in the mixture.

According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.

The given partial pressure of gases in the mixture has been:

Partial pressure of Nitrogen, $P_N_2=3\;\rm atm$
Partial pressure of Oxygen, $P_O_2=1.80\;\rm atm$
Partial pressure of Argon, $P_A_r=0.29\;\rm atm$
Partial pressure of Helium, $P_H_e=0.18\;\rm atm$
Partial pressure of Hydrogen, $P_H=0.10\;\rm atm$

The total pressure of the gaseous mixture has been:

$P=P_N_2\;+\;P_O_2\;+\;P_A_R\;+\;P_H_e\;+\;P_H\\P=3\;+\;1.80\;+\;0.29\;+\;0.18\;+\;0.10\;\text {atm}\\P=5.37\;\rm atm$

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
