How Calculated It's The molar mass 'M', z.B. of Water (H2O)?
Hinweis: Notes: How This The word molar mass Yes, I did. Says … a Mol to take into account.
Lösung: For this purpose will be This Periodic system ('PSE') Required. calculation z.B. for Water, H2O.
- By H is on to the PSE 1.00794 (g/mol), In the case of Oxygen 15.9994 (g/mol).
This That's right. So what do you mean?, that a mol The Weight of Hydrogen atoms 1.00794 g, and by analogy a mol O-Atoms 15.9994 g. - One of them (!) only Water molecule is shown 2 Hydrogen atoms and a Oxygen atom on
- One of them mol (!) Water molecules to be wise This means that 2 mol H-Atoms and 1 mol O-Atoms on.
- The molar mass Calculated The Commission This means that to 2·1.00794 + 1·15.9994 = 18.01528 g or rounded 18 g/mol on.
- In Short form written: M(H2O) = 18 g/mol
