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?
