If the pH is 3.94 what is the concentration of H

If pOH is 3.05, pH is 10.95 or

[H+]=1.122⋅10−11 mol/L

Explanation:

pH=−log(H+)Now, what is H+

if your pH is 10.95 (since pH+pOH=14, your pH=10.95).

(H+)=10 −10.95

(H+)=1.122⋅10 −11

This is your hydrogen ion concentration: [H+]=0.00000000001122  mol/L

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
