Consider separate 100.0 gram samples of each of the following: H2O, N2O, C3H6O2, CO2 Determine which 100.0 gram sample will have the greatest number of oxygen atoms and list them in order from greatest to least.

Answer : The sample has greatest number of oxygen atoms.

The order of number of oxygen atoms from greatest to least will be:

Explanation :

First we have to calculate the moles of

Molar mass of = 18 g/mol

and,

Molar mass of = 44 g/mol

and,

Molar mass of = 74 g/mol

and,

Molar mass of = 44 g/mol

Now we have to calculate the number of oxygen atoms in

In :

As, 1 mole of contains number of oxygen atoms

So, 5.55 mole of contains number of oxygen atoms

In :

As, 1 mole of contains number of oxygen atoms

So, 2.27 mole of contains number of oxygen atoms

In :

As, 1 mole of contains number of oxygen atoms

So, 1.35 mole of contains number of oxygen atoms

In :

As, 1 mole of contains number of oxygen atoms

So, 2.27 mole of contains number of oxygen atoms

The order of number of oxygen atoms from greatest to least will be:
