WebSignificant digits from common measurements. Mass – analytical balances generally give many significant digits, particularly when weighing 0.1 g or more, you get 4, 5, or 6 significant digits. For example, 0.5012 g of a substance has 4 significant digits. Higher masses give you more significant digits until you reach the capacity of the balance. Web12.0015 has 6 sig figs No decimal numbers (integers) with no trailing zeros: In general, the same rule above applies if it is an integer with a non-zero last digit such as 135, 34, 1254, etc... each and every digit is significant here. We assume that there was a good reason to include all those digits.
Why are there only 2 significant figures in the answer?
Web12 mrt. 2024 · The last common sig DP between 0.997 and 0.99717 is the third decimal place, so the result of your subtraction, when rounded to the correct number of sig figs is zero. Here is the more important part and the rational behind the sig fig rules... 0.997 g/mL implies a precision of +/- 0.001g/ml.
