Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451

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
