    16.09 because you can only have the smallest amount you already have of sig figs do you udnerstand?

    The final answer cannot have more places after the decimal than any of the given measurements. The final answer cannot have a final digit, which represents the uncertain or estimated place, farther to the right than any of the final digits in the measurements used. for addition and subtraction

    Only given measurements affect the number of sig figs allowed in the final answer. Equivalences used to convert units do not affect the sig figs allowed in the final answer because they are memorized relationships that were not measured with a specific instrument. If you are only given one measurement, the total number of sig figs in that measurement equal the total number of sig figs allowed in your final answer. If you are given more than one measurement to be used in a calculation, the final answer must be rounded to the same total number of sig figs as the measurement that has the least total sig figs. for division and multiplication
