Well, what are the molar masses of each element?
Explanation:Silicon, 28.1⋅g⋅mol−1 .
Selenium, 79.0⋅g⋅mol−1 .
Tin, 118.7⋅g⋅mol−1 .
Sulfur, 32.1⋅g⋅mol−1 .
And clearly, because silicon has the LOWEST atomic mass, a 2.00⋅g mass of silicon, has the GREATEST number of atoms. How many atoms does this mass of silicon contain?
