Answer:
2.16 * (10^-5).
Step-by-step explanation:
5 = -log H+
5 = log (1 / H+)
1/ H+ = 10^5
H+ = 10^-5
In a similar fashion the other brand has H+ of 10^-4.5.
So the difference in hydrogen ion concentration = 10^(-4.5) - 10^(-5)
= 2.16 * (10^-5).
4 1/2 or 4.5 (which ever you prefer)
Just multiply 6 by 3/4 for the answer.
I don't know exactly i think its either 3 grams or 7 grams or 2 1/2 grams
sorry if its wrong
