Explanation:
The mass of an electron expressed in standard form is 9.11x10-31, which is the same thing as 0.000000000000000000000000000000911, while the former looks compact and easier to understand, the latter is clumsy,
The concept of three significant figures mean, three non-zero figures, in other words, provide your answer in an approximate form using three figures apart from zero, so you would try to express your answer in such a way that the first digit in your answer is not zero, in this case, its a "nine" - "9", and the other two significant figures are "1" and "1".
