First let's calculate the formula mass of SiO2. It is 28.1 + 2(16.0) = 60.1. The amount of SiO2 can be calculated as 6.54/60.1 = 0.109mol. Now in one formula unit of SiO2 there is one Si atom. So, the amount of Si atoms present is 0.109mol. To get the numerical quantity, multiply it by the Avogadro's constant, and we get 0.109 × 6.02 × 10^23 = 6.55 x 10^22 atoms

How many silicon atoms are there in 1.00 g of silicon?
Silicon is a common metalloid which is a chemical element but it is considered to be tetravalent metalloid which has only 4 available electrons for covalent chemical bonding in its valence region. In the periodic table, Silicon has atomic number 14 with Si symbol. It is good to know that silicon is less reactive that Carbon-14 based on its position in the periodic table which is in the bottom of Carbon. The Standard Atomic Weight for Silicon is 28.0855 grams. The standard is based on the Avogadro's Constant which is 6.02214179 x 1023 mol-1. 1 mol of silicon will contains 6.02214179 x 1023 atoms of silicon.
