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).

Your problem is:
$35.00 is what percentage of $437.50?
If you are given a part and the whole, and you want to know what percent the part is of the whole, divide the part by the whole and multiply by 100.
In this case, the whole is $437.50.
The part is $35.00.
35/437.5 * 100 = 8%
