Question 1131039: Use the acidity model
pH = −log[H+],
where acidity (pH) is a measure of the hydrogen ion concentration [H+] (measured in moles of hydrogen per liter) of a solution.
Compute [H+] for a solution in which pH = 4.1. (Enter your answer in scientific notation. Round the decimal value to two decimal places.)

-log%28%28H%29%29=4.1

log%28%28H%29%29=-4.1

10%5E%28-4.1%29=H

[H+] = 7.9 x 10^(-5) molar

7.94 x 10^(-5) to two decimal places
