If an average silicon atom weighs 28.09 amu, how many silicon atoms are contained in 6.96 x 10^13 amu of silicon? what will 3.16x 10^23 silicon atoms weigh?

Well, what are the molar masses of each element?

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?

answer: h+ its less than oh

i don,t know so just answer mine
