In this question, we are assigned to the task to identify the species which contains most atoms.
00:09
The species are given as 10 .0 gram beryum, 10 .0 gram aluminum, 10 .0 gram aluminum, 10 .0 gram rubidium, 10 .0 gram calcium, and 10 .0 gram lithium.
00:30
Now, we know that the number of atoms is equals to moles multiplied by avagadro's number.
00:41
Moles is mass divided by molar mass.
00:46
In all the cases, mass is same and avagadro number is a constant.
00:52
The value is fixed point 022 into tanges to the power 23.
00:58
They suggest that the number of atoms will depend on the molar mass and they suggest that the number of atoms is inversely related to the molar mass.
01:12
Now in this case the molar mass of barium is 137 .327 gram per mole...
