<p>that equation isn’t on the equation sheet, i don’t beliebe</p>

<p>and logs may show up… i know they show up on ap chem… if there are any logs (probably won’t be any; if there are, only one or two at most i’d think) then just think of shortcuts… like log(5x10^-3) is about equal to 2.5 ish (between log(1x10^-2) and log(1x10^-3))… it’s really 2.3… but 2.5 is a close enough estimate</p>
