Explanation:
lowest point of liquid or meniscus
Answer: 64
Explanation:
you just multiple the 3 numbers to get the answer (i’m in chemistry and just did this question lol)
<span>[H3O+] = 10^(-pH) = 10^(-4.20) = 6.3 x 10^-5 M
pOH = 14 - pH = 14 - 4.20 = 9.80
[OH-] = 10^(-pOH) = 10^(-9.80) = 1.6 x 10^-10 M
</span>
The correct answer is 13 I just did it bro
