Answer:
um thats tricky man
Explanation:
i dont even know what nuclei is
Wait, do we do both of the places or only the types of elements because i don't understand...
PH + pOH = 14
12.52 + pOH = 14
pOH = 14 - 12.52
pOH = 1.48
[OH⁻] = 10^ -pOH
[OH⁻] = 10 ^- 1.48
[OH⁻] = 0.033 M
15mL because if it started as 20 mL and went to 35mL when u put in pyrite, the pyrite takes up 15mL
