Five molecules of propane have 40 hydrogen atoms.
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
12.044*10^23 atoms 1.5055*10^23 S8 molecules
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
Propane has a density of .0018794 g/cm3. in 22.4 liters, there are 22400 cm3, so there are 42.10 grams of propane. The molar mass of propane is 44.10 g/mole, so there are .955 moles. Via Avogadro's number, there are then 5.751 E23 molecules of propane present.

Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
The answer is 0,166.10e23 molecules.
0,34 g HCl contain 5,6.10e21 molecules.

No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
there are 2 atoms of hydrogen in water
