How many moles of H3O are present in an 85 L solution with a pH of 3.0?
To find the number of moles of H3O in the solution, you can use the formula pH -logH3O. First, calculate the concentration of H3O ions using the pH value: pH -logH3O 3.0 -logH3O H3O 10(-3.0) 1.0 x 10(-3) M Next, calculate the number of moles of H3O in the solution using the concentration and volume: moles concentration x volume moles 1.0 x 10(-3) mol/L x 85 L moles 8.5 x 10(-2) moles Therefore, there are 8.5 x 10(-2) moles of H3O present in the 85 L solution with a pH of 3.0.

How to Evaluate the ratio MH plus pH 3 divided by MH plus pH 7?
To evaluate the ratio MH plus pH 3 divided by MH plus pH 7, first determine the molar concentration of each species at pH 3 and pH 7 using the Henderson-Hasselbalch equation. Then calculate the ratio of the concentrations of MH at pH 3 to pH 7, and divide this by the ratio of pH 3 to pH 7.
What is the pH for a solution that has h plus equals 3.6 x 10 -9 M?
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
