Significant figures are very important when it comes to calculations. If the mass of an electron is 9.10939 x 10-31 then its significant figures are: 9 x 10^-31( correct 1 significant figure), 9.1 x 10^-31 kg ( correct to 2 significant figures), 9.11 x 10^-31 (correct to 3 significant figures), and 9.109 x 10^-31 (correct to 4 significant figures).
When rounding 1286 to 2 significant figures, you must consider the first two non-zero digits from the left. In this case, those digits are 1 and 2. The digit to the right of 2 (8) is greater than 5, so you round up. Therefore, 1286 rounded to 2 significant figures is 1300.
