Four gases were combined in a gas cylinder with these partial pressures: 3. 5 atm N2, 2. 8 atm O2, 0. 25 atm Ar, and 0. 15 atm H
aksik [14]

The total pressure of the gas has been 11.9 atm.

The partial pressure has been the pressure exerted by the individual gas in the mixture.

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

<h3 /><h3>Computation for the pressure of gas</h3>

The given gas has partial pressure of Nitrogen, P_{N_2}=3.5\;\rm atm

The partial pressure of Oxygen, P_{O_2}=8\;\rm atm

The partial pressure of Argon, P_{Ar}=0.25\;\rm atm

The partial pressure of Helium, P_{He}=0.15\;\rm atm

The total pressure, (<em>P</em>) of the gas has been given as:

P=P_{N_2}\;+\;P_{O_2}\;+\;P_{Ar}\;+\;P_{He}\\&#10;P=3.5\;+8\;+\;0.25\;+\;0.15\;\text{atm}\\&#10;P=11.9\;\rm atm

The total pressure of the gas has been 11.9 atm.

Calculate the pH of a solution prepared by mixing 50.0 mL of 0.125 M KOH and 50.0 mL of 0.125 M HCl .
Nitella [24]

Answer: 7

Explanation:

50 ml 0.125 M KOH = (50 * 0.125) = 6.25 ml 1 M KOH

similarly 50 ml 0.125 M HCl = 6.25 ml 1 M HCl

so KOH will fully neutralize the HCl so the pH of the medium will be 7

H+ + OH- = H2O

so Kw = [H=][OH-]

= [H+]^2 = 10-14

SO [H+] = 10-7

pH = -log [H+]

pH = -log[10-7]

pH = 7
