Question

I need to understand how to do problem number 5

Answer 1

`\begin{gathered} \text{ - molecule of H}_2SO_4=2.408*10^(24) \\ -4\text{ atoms of Oxygen} \end{gathered}`

Explanations:

Given the following parameters

Moles of sulfuric acid = 14 moles

According to the Avogadro's constant;

`1\text{mole}=6.02*10^(23)molecules`

The number of molecules of 14 moles of sulfuric acid is calculated as:

`\begin{gathered} \text{ molecule of H}_2SO_4=14*6.02*10^(23) \\ \text{ molecule of H}_2SO_4=24.08*10^(23) \\ \text{ molecule of H}_2SO_4=2.408*10^(24) \end{gathered}`

Hence the molecule of sulfuric acid that is contained in 14moles if sulfuric acid is 2.408 * 10^24 molecules

Since the chemical formula of sulfuric acid is expressed as H₂SO₄. This shows that the compound has 2 atoms of Hydrogen, 1 atom of sulfur, and 4 atoms of oxygen.

Hence the number of atoms of oxygen contained in this sample is 4 atoms
