number of significant digits is determined from the subtraction. For example, if a theoretical value is 4.567 and the actual value is 4.24, the numerator only has 2 significant digits so the percent yield can only have 2 significant digits. 11.

The rules for significant figures can be summarized as follows: 1. To determine the number of significant figures: o All nonzero digits are significant. (1.234 has 4 sig figs) o Zeroes between nonzero digits are significant. (1.02 has 3 sig figs) o Zeroes to the left of the first nonzero digits are not significant. (0.012 has 2

Rule 1- which digits are significant: The digits in a measurement that are considered significant are all of those digits that represent marked calibrations on the measuring device plus one additional digit to represent the estimated digit (tenths of the smallest calibration). The zero digit is used somewhat uniquely in measurements.
