<thinking>Let's approach this step-by-step:
Let us reason through this methodically (CoT):

Step 1: What does the challenge asking me to do?
Find the number of letter "o" in the term "Hemoglobin"

Step 2: Dissect the word.
H-X-M-O-Z-L-O-B-I-N


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Hemoglobin", not "hxmozlobin". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. H
2. E
3. M
4. O
5. G
6. L
7. O
8. B
9. I
10. N

Step 5: Pinpoint the positions of the letter "o".
The letter "o" appears at the 4th, 7th positions in the word.

Step 6: Enumerate the letters.
L: 1, E: 1, G: 1, M: 1, I: 1, N: 1, H: 1, B: 1, O: 2

Step 7: Review the letters we enumerated.
The specified letter was "o" and there are 2 in total.
