The pH of a solution is a measure of the quantity of hydrogen atoms (H) in the solution. It is given by the formula f(x) = −log x. In the formula, x = [H+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

The question is incomplete. The complete question is :

The pH of a solution is a measure of the quantity of hydrogen atoms (H) in the solution. It is given by the formula f(x) = −log x. In the formula, x = [H+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

The approximate molar concentration of several chemicals are given. Find the pH of each. Use the calculator and round to the nearest tenth, if necessary.

Oven cleaner: [H+] = 10−13 pH =

Water: [H+] = 0.0000007 pH =

Blood: [H+] = 0.00000004 pH =

Vinegar: [H+] = 0.0063 pH =

Solution :

Given formula :

f(x) = −log x

Here,  x = [H+] = molar concentration of hydrogen atoms

Therefore, the pH of each of the following solution are :

Oven cleaner

[] =

pH = - log []

     =

     = 13

Water

[] = 0.0000007

pH = - log []

     = - log 0.0000007

     = 6.2

Blood

[] = 0.00000004

pH = - log []

     = - log 0.00000004

     = 7.4

Vinegar

[] = 0.0063

pH = - log []

    = - log  0.0063

    = 2.2

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
