3.30 gSiO2 / 60.085g SiO2 x 2 mol 0 / 1 mol SiO2 x (6.022*1023 )= 6.61*1022 O atoms
Quartz, silica has a formula unit of SiO2. There are three atoms in a formula unit. SiO2 is a giant molecule with silicon atoms linked to four oxygen atoms which each link across to another silicon atom, this is different from CO2 which is molecular gas.
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
The number of atoms is 1,50553521.10e23.
Silicon dioxide is SiO2 and contains 3 atoms.

The molecular formula for silicon dioxide is SiO2, so there are a total of three atoms; one silicon atom, and two oxygen atoms.

Ans:Quartz is SiO2. It has a formula weight of 60.1 g/mol. 3 grams of SiO2 is 0.05 moles.Each mole of SiO2 has 0.1 moles of oxygen since there are 2 oxygen atoms per formula unit of SiO2.(1 mole of anything is 6.02x1023 of anything.)0.1 mol oxygen atoms x 6.02x1023 oxygen atoms / mol oxygen atoms= 6.02 x 1022 oxygen atoms.Number of O atoms =6.02×1022
Sand is silicon dioxide, formula SiO2
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
The compound silicon monoxide (SiO) has only two atoms; one silicon atom, one oxygen. The prefix "mono" tells you there is only one oxygen attached; "bi" or "di" (such as in silicon dioxide) would tell you there are two oxygens (for total of three, in that example).
The number of atoms is 1,50553521.10e23.
The chemical formula of Silicon dioxide is SiO2. Two oxygen atoms are bond to a silicon atom. This compound has 3 atoms per molecule.
Approx. 9.1024 atoms.
