<h3>Answer:</h3>

pH = 8.66

<h3>Explanation:</h3>
  • The pH refers to the acidity or alkalinity of a solution.
  • It is calculated by getting the negative logarithm of Hydrogen ions concentration.
  • pH=-log[H⁺]

In this case;

we are given [OH⁻] as 4.6 x 10^-6 M

We are required to calculate the pH

We need to know that;

pH + pOH = 14

pOH = -log[OH⁻]

To get the pH we can calculate the pOH first,

pOH = -log[4.6 x 10^-6 M]

        = 5.34

but, pH + pOH = 14

Therefore, pH = 14 - pOH

                        = 14 - 5.34

                        = 8.66

Therefore, the pH of the solution is 8.66

4. How many atoms are in 32.6 g of Oxygen?
Natali5045456 [20]

Hey there!

Oxygen has a molar mass of 16. That means 16g of oxygen is 1 mole.

32.6 ÷ 16 = 2.0375 moles

We have 2.0375 moles.

There are 6.022 x 10²³ atoms in one mole.

2.0375 x 6.022 x 10²³

1.3 x 10²⁴

There are 1.3 x 10²⁴ atoms in 32.6 grams of oxygen.

Hope this helps!
