A) .00000765 =  _______ x 10 _______ 
Calculate the pH of this amount above using the formula
pH = - log10[H+]:
*if .00000765 is [H+]
B) pH = _______ 

The measure of acidity of a liquid is called the pH of the liquid. This is based on the amount of hydrogen ions (H+) in the liquid. The formula for pH is:

pH = −log[H+]

where [H+] is the concentration of hydrogen ions, given in a unit called mol/L (“moles per liter”).

Liquids with a low pH (down to 0) are more acidic and those with a high pH are more basic.

If the pH of a sample is 3.5. Then what is the [H+] concentration? Use the formula.
pH = −log[H+]

[H+] = _______ 
What is the above answer in scientific notation?
_______ x 10 _______
