How many oxygen atoms are in 3.30 of quartz?

Answer 1

3.30 gSiO2 / 60.085g SiO2 x 2 mol 0 / 1 mol SiO2 x (6.022*1023 )

= 6.61*1022 O atoms

Answer 2

Quartz is represented by the chemical formula SiO2, which means each molecule of quartz contains one oxygen atom. To calculate the number of oxygen atoms in 3.30 g of quartz, you would need to convert grams to moles of SiO2 (60.08 g/mol) and then use the mole ratio of SiO2 to oxygen to find the number of oxygen atoms. The total number of oxygen atoms in 3.30 g of quartz can be calculated as follows: 3.30 g SiO2 * (1 mole SiO2 / 60.08 g SiO2) * (2 moles O / 1 mole SiO2) * (6.022 x 10^23 atoms / 1 mole O).
