Which sample contains the greatest number of atoms?
(a) 27.2 g Cr
(b) 55.1 g Ti
(c) 205 g Pb
Here, we have to determine the sample contains the greatest number of atoms :
One mole of any element contains Avogadro number of particles, that is 6.0221023 particles. Based on this concept, we will find the sample that has greater number of atoms.
Steps to find the number of atoms :
1. Use the periodic table and get the molar mass of each element.
2. Divide the given mass of the sample by the molar mass of each element this gives the number of moles.
3. Multiple a mole by 6.022 1023, which gives you the number of atoms. And there is your answer.
