Answer : The percent composition of Pb and Sn in atom is, 3.21 % and 96.8 % respectively.
Explanation :
First we have to calculate the number of atoms in 5.5 wt% Pb and 94.5 wt% of Sn.
As, 207.2 g of lead contains atoms
So, 5.5 g of lead contains atoms
and,
As, 118.71 g of lead contains atoms
So, 94.5 g of lead contains atoms
Now we have to calculate the percent composition of Pb and Sn in atom.
and,
Thus, the percent composition of Pb and Sn in atom is, 3.21 % and 96.8 % respectively.
