pH of garden soil = pH 6
pH of peat moss = pH 4
How much greater is the concentration of hydrogen ions in the peat moss than in the garden soil????

pH= -log [H+]
6 = - log [H+] (garden soil), So [H+] = 10 ^ (-6)
4 = - log [H+] (peat moss), So [H+] = 10^ (-4)
10^ (-4) / 10 ^ (-6) = 10^2 = 100
so the concentration of hydrogen ions in the peat moss is 100 times greater than in the garden soil.

Hydrogen concentration : [H+]
Garden soil:
pH = 6
[H+] = 10^(-6)
Peat moss:
pH = 4
[H+] = 10^(-4)
(10^(-4)) : (10^(-6)) = 100

100 times greater. You take the difference in pH and use 10 to the power of that to get the difference in actual concentration. It's a logarithmic scale.

well you know that pH4 is stronger pH than pH6. So pH 4= 10^-4 and pH6= 10^6. So now you divide 10^-4 by 10^-6 gives you 100.
