How many oxygen atoms are in 2.60g of quartz?

Answer 1

This is a complex tetrahedral formula, but SiO2 is the accepted formula for our purposes. I assume you mean 1.40 grams quartz.

1.40 grams SiO2 (1 mole SiO2/60.09 grams)(2 mole O/1 mole SiO2)(6.022 X 10^23/1 mole O)

= 2.81 X 10^22 atoms of oxygen

( may need the tetrahedral formulation. In this form the O2 is shared and the form is SiO4. So, same ratios, different numbers. SiO2 is standard though )

Answer 2

2.60 grams SiO2 (1 mole SiO2/60.09 grams)(2 mole O/1 mole SiO2)(6.022 X 10^23/1 mole O)

= 5.21 X 10^22 atoms of quartz

( SiO2 is standard formulation, but SiO4 is actual tetrahedral structure of quartz, Change numbers if needed, but approach is the same )

Answer 3

I think quartz is, SiO2, but if not the procedure here will remain the same.

2.20 grams SiO2 (60.09 grams/1 mole SiO2)(2 mole O/1 mole SiO2)(6.022 X 1023/1 mole O)

= 4.41 X 1022 atoms of oxygen

=======================

Answer 4

2.81 × 1022 atoms of oxygen according to Wolfram|Alfa in the link below.

Answer 5

Quartz has the chemical formula O2Si. The molecular mass is 60.0843 grams per mole, so there are 38.3 millimoles. There are then 76.3 millimoles of O2 or 4.595 E22atoms of O2.

Answer 6

There are 6.82*10^22 oxygen atoms int 3.40 grams of quartz.

Answer 7

5.22 * 10^22

Answer 8

4.82x1022

Answer 9

5.82*1022
