Calculate the molar mass FeCl3 Fe2(SO4)3 PbO PbO2 Pb3O4

To find molar mass: look for each element on the table and find their atomic masses. Then add each atomic mass to find the molar mass. If there is a subscript then that means that there is 3 of that number. For atomic mass round to the nearest hundredths
FeCl3= 162.2
Fe2(SO4)3= 354.88
PbO=223.2
PbO2 = 239.2
Pb3O4=685.6

What is the pH if the [H+] concentration is 3 x10^-13

Shkiper50 [21]

Answer:

pH = 12.52

Explanation:

Given that,

The [H+] concentration is $3\times 10^{-13}$ .

We need to find its pH.

We know that, the definition of pH is as follows :

$pH=-log[H^+]$

Put all the values,

$pH=-log[3\times 10^{-13}]\\\\pH=12.52$

So, the pH is 12.52.
