Sig figs in exponents
WebSo think of it like this for pH and sig figs. The number (digits) in front of the decimal are really just putting us in the right power of 10 range like the exponent of 10 in a scientific notation number. Those leading digits in front of the decimal are NOT significant. Now, the numbers AFTER the decimal - those are the sig figs. WebThe mantissa is .021 and has 3 digits because 10.5 has 3 sig figs). NOTE: It is the number of digits , not the number of sig figs in the mantissa 7. For exponents, the number of sig figs is the same as the number of digits in the mantissa. For example 101.23 = 17 or 1.7 x 101. This has 2 sig figs because there are 2 digits in the mantissa (.23). 8.
