Step-by-step explanation:
Let us assume that the amount deposited = P
The rate of interest = 1.4%
The Simple Interest earned = $24.50
Time = T = 5 years
Now, as we know:
SIMPLE INTEREST =
Hence, the deposited sum of money by Edwin is $350.
ok. We are given the following equation:
Where:
Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:
Now, we will use the following property of logarithms:
Applying the property and having into account that:
We get:
Now we substitute the given value of "pH = 4.5":
Solving the operation:
Therefore, the hydrogen ion concentration of the fluid is 0.000032
