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

Step 1: What is the task asking me to do?
Determine the frequency of character "x" in the term "Hemoglobin"

Step 2: Deconstruct the word.
H-E-M-O-G-L-O-B-I-N


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

Step 3: Determine the positions of the letter "x".
The letter "x" does not appear in the word.

Step 4: Count the letters.
L: 1, E: 1, G: 1, M: 1, I: 1, N: 1, H: 1, B: 1, O: 2

Step 5: Review the letters we counted.
The target letter was "x" and there we identified 0 total.

Final answer:
The letter "x" is found 0 instances in "Hemoglobin".</thinking>
