Carbon (C) contains the largest number of moles.
Number of Moles of a substance can be defined as the ratio of given mass of the substance to the Molecular Mass of the substance.
We can write,
Number of moles = Given Mass / Molecular Mass euation1
Given Mass of Na, C, Pb, Cu, Ne each = 10.0g
Molecular mass of Na = 22.9898 u
Molecular mass of C = 12u
Molecular mass of Pb = 207.2u
Molecular mass of Cu = 63.546 u
Molecular mass of Ne = 20.1797 u
After substituting the values of molecular mass and given mass of elements in equation1 , we will get
Number of moles of Na = (10/22.9898) = 0.4350
Number of moles of C = (10/12) = 0.8333
Number of moles of Pb = (10/207.2) = 0.0483
Number of moles of Cu = (10/63.546) = 0.1574
Number of moles of Ne = (10/20.1797) = 0.4955
So, we can clearly see that Carbon contains the largest number of moles.
