1) Silicon dioxide formula: SiO2 ... 2 is a subscript for the O atom

2) From the formula you have 1 molecula of SiO2 contains 1 atom of SiO2

3) Then, 0.100 mol of SiO2 contains 0.1 mol of Si

4) Multiply by Avogadro's number: 0.100mol * 6.022*10^23 atoms/mol = 6.02*10^22 atoms

Answer: 6.02*10^22 atoms
