Answer:

.4998 atm    ( rounded to .5 atm   ) <===== not one of the answers listed

Explanation:

The partial pressure exerted by O2   is   equal to the fraction that is O2 times the pressure

1.5 / ( 1.5 + 1.2 + .301 )   * 1 atm = .4998 atm  

<u>( 1) Are you sure it is   ONE atm pressure in the container?</u>

A 10.0 ml portion of 0.010 m hcl is diluted by adding it to100.0 ml of water. what is the ph of the solution
Volgvan

From the calculation, the pH of the solution after dilution is 3.

<h3>What is the pH?</h3>

The pH is the hydrogen ion concentration of the solution. Now we know that;

C1 =  0.010 m

V1 = 10.0 ml

V2 = 10.0 ml + 100.0 ml = 110 ml

C2 = ?

C1V1 = C2V2

C2 = C1V1 /V2

C2 =  0.010 m  * 10.0 ml / 110 ml

C2 = 0.00091 M

pH = -log[0.00091 M]

pH = 3
