Answer:
depends...
on how difficult it is
Size and Temperature or E & B
Explanation:
223.6539
1 mole is equal to 1 moles KCl, or 74.5513 grams
The answer is 5.10
We know that
pH + pOH = 7
pOH = 7 – pH
pOH = 7 – 1.90
pOH = 5.10
Thus, The pOH of the solution is 5.10
nitric acid - HNO3
Hope it's correct! :)
