Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
<span>So, when you make something boiling or melting, its still the same substance. Water doesn't change into something else, just change its state of matter. When you burn something, one substance reacts with another. For example, when you burn carbon in oxygen, you get carbon dioxide. That's the difference.</span>

Answer : The molar mass of hemoglobin is, 
Explanation : Given,
Molar mass of iron = 55.85 g/mol
0.349 % Fe by mass that means 0.349 grams of Fe present in 100 grams of hemoglobin.
or,
Now put all the given values in this formula, we get:
Thus, the molar mass of hemoglobin is,
