Why did the chemist study helium? Because he found it quite uplifting!
Now, let's calculate the number of atoms present in 3.4g of H2S!
To do that, we need to use the concept of moles and Avogadro's number. The molar mass of H2S is approximately 34 g/mol.
First, we calculate the number of moles using the formula:
Number of moles = mass / molar mass
Number of moles = 3.4g / 34 g/mol = 0.1 mol
Since H2S has two hydrogen atoms and one sulfur atom, there are three atoms in total per molecule. So, to calculate the number of atoms, we multiply the number of moles by Avogadro's number (6.022 x 10^23):
Number of atoms = Number of moles x Avogadro's number
Number of atoms = 0.1 mol x 6.022 x 10^23 atoms/mol
Number of atoms â 6.022 x 10^22 atoms
So, there are approximately 6.022 x 10^22 atoms in 3.4g of H2S. That's a whole lot of atoms! Keep in mind that this calculation assumes 100% purity of the compound.
