Explanation:
(a) As per the mole concept, one mole of any atom contains
atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of
=
molecules
=
molecules
1 mole of
=
molecules
=
molecules
1 mole of
=
molecules
=
molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of
contains 2 atoms of hydrogen.
So, mass of 1 mole of
= ![2 mol \times 1.008 g/mol](https://tex.z-dn.net/?f=2%20mol%20%5Ctimes%201.008%20g%2Fmol)
= 2.016 g
mass of 1 mole of
= ![2 mol \times 15.999 g/mol](https://tex.z-dn.net/?f=2%20mol%20%5Ctimes%2015.999%20g%2Fmol)
= 31.996 g
mass of 1 mole of
= ![2 mol \times 18.998 g/mol](https://tex.z-dn.net/?f=2%20mol%20%5Ctimes%2018.998%20g%2Fmol)
= 37.996 g
Thus, we can conclude that
has the greatest mass.
In my point of view, the simple thing to do here is just to exchange the 3+ and the 2- and you will get:
Al2(CO3)3
The logic behind this is that when you have 2 Al^3+, it makes an overall charge of 6+. Additionally, when you have 3 CO^2-, it also makes an overall charge of 6- (because 3 X 2 = 6). Therefore, 6+ and 6- "cancelled" out, and you will have a neutral charge compound.
I hope you understand
