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:
