Calculate the amount of hydrogen atoms in 0.75 mol of water molecules
0.75 mols H2O so there are 1.50 mols H atoms and there are 6.02E23 atoms in a mols of anything.
To calculate the number of hydrogen atoms in 0.75 mol of water molecules, we'll first determine the number of water molecules in 0.75 mol, and then multiply that by the number of hydrogen atoms in each water molecule.
Step 1: Calculate the number of water molecules in 0.75 mol.
Avogadro's number, 6.022 x 10^23, represents the number of particles (atoms, molecules, etc.) in one mole of a substance.
So, we can use Avogadro's number to convert moles to molecules.
Number of molecules = Number of moles x Avogadro's number
Number of molecules = 0.75 mol x 6.022 x 10^23 molecules/mol
Step 2: Determine the number of hydrogen atoms in each water molecule.
A water molecule (H2O) contains 2 hydrogen atoms.
Step 3: Multiply the number of water molecules by the number of hydrogen atoms in each molecule.
Number of hydrogen atoms = Number of water molecules x 2
Substituting the calculated values:
Number of hydrogen atoms = 0.75 mol x 6.022 x 10^23 molecules/mol x 2
Now, let's calculate the number of hydrogen atoms in 0.75 mol of water molecules.
Number of hydrogen atoms = 0.75 mol x 6.022 x 10^23 molecules/mol x 2
Number of hydrogen atoms = 9.033 x 10^23 hydrogen atoms
Therefore, there are approximately 9.033 x 10^23 hydrogen atoms in 0.75 mol of water molecules.
To calculate the number of hydrogen atoms in a specific number of moles of water molecules, we will need to use Avogadro's number and the molecular formula of water.
Avogadro's number (represented by "N") is defined as 6.022 x 10^23 particles per mole. In this case, we will be using it to find the number of water molecules.
The molecular formula of water is H2O, indicating that each water molecule contains 2 hydrogen (H) atoms.
Here's how you can calculate the number of hydrogen atoms in 0.75 mol of water molecules:
Step 1: Determine the number of water molecules
To calculate the number of water molecules in 0.75 mol, multiply the given number of moles by Avogadro's number:
Number of water molecules = 0.75 mol x (6.022 x 10^23 molecules/mol)
Step 2: Calculate the number of hydrogen atoms
Since each water molecule contains 2 hydrogen atoms, multiply the number of water molecules by 2:
Number of hydrogen atoms = Number of water molecules x 2
Now, let's do the calculations:
Number of water molecules = 0.75 mol x (6.022 x 10^23 molecules/mol)
Number of water molecules = 4.517 x 10^23 molecules
Number of hydrogen atoms = Number of water molecules x 2
Number of hydrogen atoms = 4.517 x 10^23 molecules x 2
Number of hydrogen atoms = 9.034 x 10^23 atoms
Therefore, there are approximately 9.034 x 10^23 hydrogen atoms in 0.75 mol of water molecules.
