I have some questions about the mineral Quartz..1) Is quartz also and ore?2) How many colors dose quartz come in and what are they?3)what are some uses for quartz besides decoration?
This is simple math. The molecular weight of quartz is 60,09 (SiO2) and therefore there are 0.0416 moles of quartz in 2.5 g. The number of atoms or molecules in a mole is 6.02 x 10 ^ 23, and so 0,0416 moles is 2.505 x 10^22 molecules of quartz. Each molecule of quartz has 2 atoms of Oxygen, so the answer you are looking for is 5,01*10^22. That will be 10 points, please.
