0,5 moles of any gas
36 grams of water is equal to 2 moles. Therefore, to find the quantity of oxygen molecules that contain the same number of molecules as 36 grams of water, you would need 4 moles of oxygen since the molecular formula of water is H2O.
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.
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
contains the same number of molecules
The total number of molecules is equal.

The membrane is permeable to water but not to sugar.

The total number of molecules is equal.
The mass of the water The number of molecules
It is the same as ordinary water except that ordinary water molecules may be mixed with a small number of molecules of solutes.
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
They both have the same number of atoms. The weight is different
36 g water contain 32 g oxygen.32 g oxygen is equivalent to 1 mol oxygen.1 mol has 6,023.10e23 molecules (or atoms, ions).
No, it takes the same number of water molecules to fill up a certain space whether they are in the form of ice or liquid water. In ice, the water molecules are just held in a more structured arrangement compared to the more freely moving molecules in liquid water.
