determine the number of sig figs / decimal places in the calculated answer. This number only has 2 Sig Figs, so the answer must be rounded to 2 SF’s. Only has 3 SF’s, so answer needs rounded to 3 SF’s. Decimal point causes the “0” to count as a SF. Because this is multiplication, the answer to this part can only have 2 SF’s.
