PH= log[H3O+]
10.25=log [H3O+]
[H3O+] = 10^10.25
[H3O+]= 1.778 ×10^10

<span>pH + pOH = 14 10.25 + pOH = 14 pOH = 14 - 10.25 = 3.75 Now, knowing the pOH we can find the OH^- since pOH is -log [OH-] [OH-] = 10^-3.75 = 1.78x10^-4 M</span>

Determine the molecular formulas for compounds having the following empirical formula and molar mass:
boyakko [2]

Answer:

C6H24S3

Explanation:

To go from Empirical Formula to Molecular Formula, you have to divide the actual amount (given) by the molar mass of the EF:

192 / 2(12.01)+8(1.01)+(32.06)

= 2.99

= 3

Then you multiply every subscript in the EF by 3, which gives you C6H24S3

Hope this helps!
