Answer:

The response is identical to 9.11x10-31kg, which refers to electron mass.

Explanation:

The mass of an electron written in scientific notation is 9.11x10-31, which translates to 0.000000000000000000000000000000911 in standard form. While the former is more compact and easily interpretable, the latter appears cumbersome.

When discussing three significant figures, it indicates three non-zero digits. Essentially, your answer should use three digits that are not zero, starting with the first digit as non-zero, which in this case is "nine" - "9", followed by "1" and "1" as the two additional significant figures.
