Logarithm sigfigs with O

Postby PriscillaLi_3G » Sat Dec 07, 2019 4:11 pm

If there is a 0 after the decimal point of a logarithmic calculation, does that count?

for example if pH=0.02, does that count as one sigfig or two?

This counts as one sigfig. Only 0s after a number after the decimal will be significant, like 0.200 will have three sigfigs.

^I understand that this is true for conventional numbers, however, for pH specifically, my TA mentioned that each number after the decimal point is a significant figure. Please double check with another source, though.
