Answer:

Step-by-step explanation:

The hydrogen ion concentration can be found by finding the antilog of the pH

$pH = - log [ {H}^(+) ]$

We have

$2.11 = - log({H}^(+)) \\ find \: \: antilog \: of \: both \: \: sides \\ \\ |{H}^(+)| = {10 }^( - 2.11) \\ = 0.00776...$

We have the final answer as

0.01 M to 2 decimal places

Hope this helps you
