Which quantity of particles is correctly represented by the formula H2SO4? Explain.
The formula H2SO4 represents a chemical compound called sulfuric acid. In this compound, H2SO4, the elements present are hydrogen (H), sulfur (S), and oxygen (O).
The subscript number '2' after the symbol H indicates that there are two hydrogen atoms in the molecule. The subscript '1' is often implied and not written, so it is assumed that there is only one sulfur atom present. The subscript '4' after the symbol O indicates that there are four oxygen atoms in the molecule.
The formula H2SO4 tells us that in one molecule of sulfuric acid, there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms. Therefore, the quantity of particles represented by the formula H2SO4 is one sulfuric acid molecule.
The formula H2SO4 represents a chemical compound called sulfuric acid. In order to determine the quantity of particles represented by the formula H2SO4, we need to understand its composition.
In the formula, H2SO4, the element symbols represent the different atoms present in the compound:
- H stands for hydrogen
- S stands for sulfur
- O stands for oxygen
The subscripts next to each element symbol indicate the number of atoms of that element present in one molecule of the compound. So, in H2SO4, there are 2 hydrogen (H) atoms, 1 sulfur (S) atom, and 4 oxygen (O) atoms in each molecule of sulfuric acid.
To determine the quantity of particles in a given amount of sulfuric acid, we need to understand the concept of Avogadro's number. Avogadro's number is approximately 6.022 × 10^23, and it represents the number of particles (atoms, molecules, or ions) in one mole of a substance.
To find the quantity of particles represented by the formula H2SO4, we need to convert the amount of sulfuric acid to moles and then multiply it by Avogadro's number, considering that one mole of H2SO4 gives you 6.022 × 10^23 molecules of H2SO4 or 6.022 × 10^23 × (2 + 1 + 4) particles in total.
For example, if we have 2 moles of H2SO4, the calculation would be as follows:
2 moles H2SO4 * 6.022 × 10^23 molecules/particles per mole = 1.2044 × 10^24 molecules/particles of H2SO4
So, in this example, 2 moles of H2SO4 would represent approximately 1.2044 × 10^24 molecules/particles of sulfuric acid.
By using this approach, you can determine the quantity of particles represented by any given amount of substances with known formulas.
