The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. what is the approximate ph of a solution if the concentration of hydrogen ions is 5.0 × 10–4 moles per liter?
2.7
3.0
3.3
3.6

The answer eould be 3.3 per liter.

i wishes i knew the reasoning but i dont, sorry

hope this helped ;)

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.
