Hi bestie lol i’m failing math too and use this app as a lil cheat :)
Step-by-step explanation:
i was busy so i did this much ...will solve later
A number=x
2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable
4*6 = 24. (4 dollars to spare)
(5*2) + (4*4) = 26 (2 dollars to spare)

POH is the -log [ OH- ]. Using this equation, simply find the -log of the OH- concentration to find the pOH:
pOH = - log ( 0.000086 ) = 4.07
