Which contains the most molecule's 1 mole of water 1 mole of glucose or 1 mole sodium chloride?

Answer 1

If you like that question, you would probably also like this one: Which has the greatest number of items: A bag of a dozen donuts, a box of a dozen apples or a carton of (a dozen) eggs.

By definition, "one mole of" could also be phrased as "one Avagadro's number of" ... Since that number is a constant, all three have the same number of molecules. Avogadro's numberis the number of atoms or molecules in a mole.

Since all molecules don't weigh the same, the molecular weight corresponds to that difference in mass.

Avogadro's number (a.k.a. Avogadro's constant) is very large, 6.0221415 × 1023to quantify things that are generally very small. Generally molecules, atoms or particles.

Answer 2

1 mole of water contains the most molecules. 1 mole of water consists of 6.022 x 10^23 water molecules, while 1 mole of glucose contains the same number of molecules, but sodium chloride separates into ions in solution, so 1 mole of sodium chloride contains 6.022 x 10^23 formula units, not individual molecules.
