Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
16.772 should be the farthest right.
The answer is $1,809.00.
Explanation:
To calculate interest rate, you must multiply the decimal version of the percentage by the original number. 7.25% as a decimal is equivalent to 0.0725, so multiplying that by 1,200 = 87. Now we must multiply that by 7 to find the amount after 7 years. The product is 609, or $609. Now we add that amount to the original number (1,200). The sum is 1809, $1,809. Therefore, your total balance after 7 years is $1,809.
