Given a solution with a hydroxide ion concentration, oh=3.73×10^-5,what is the ph

Explanation:

pOH is the negative logarithm of the molar concentration of hydroxide ions and pH is the negative logarithm of the concentration of hydronium ions.

The mathematical expression to determine pOH is:

Where [OH⁻] means the molar concentration of hydroxide ions.

Substituting:

pH and pOH are related by the equation:

From which:

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
