Answer:

158

Step-by-step explanation:

The input is 6.185/10.000 = 0.6185 of the full-scale of the A/D converter. If a 10V input is represented by a register value of 255, then the expected register value for this input is about ...

0.6185·255 = 157.7175 ≈ 158

_____

In hexadecimal, that is 9E.
