How many significant figures are in the answer when you divide 486.02 by 0.056?

Answer 1

1. The rule when multiplying or dividing is that you cannot have more sig figs in the answer than the least number of sig figs in the data. The number 0.056 has 2 sig figs (while 486.02 has 5). So, after dividing you would round the answer to 2 sig figs, hence 8.679 x 10³ would become 8.7 x 10³
