I think the answer is C or B.
Because they are chemically combined
Answer:
10
Explanation:
Basically same as last question but the number is before the compound :)
Did you mean the atomic mass?
Answer: The concentration of hydrogen ions for this solution is .
Explanation:
Given: pOH = 11.30
The relation between pH and pOH is as follows.
pH + pOH = 14
pH + 11.30 = 14
pH = 14 - 11.30
= 2.7
Also, pH is the negative logarithm of concentration of hydrogen ions.
Substitute the values into above formula as follows.
Thus, we can conclude that the concentration of hydrogen ions for this solution is .
