I wanted a Rose Quartz pendant or ring to wear with my Moldavite pendant. But since the Rose Quartz was cut, I can't tell if it is real. Is it?
Pure quartz consist of SiO2. The molecular weight of SiO2 is actually Si= 28 O2= 32 combined this gives you a total of 60 g/mol so you would then take 1.30g / 60 g/mol = .02167 so since there are 2 Oxygen atoms then you multiply= .02167 x 2= .04333 Then you take .04333 x 6.022 x10^23 = 2.61 x10^22
1.30gSiO2 x [32gO / 60gSiO2] x [6.02E23atoms O / 16gO] =
Pure quartz has a molecular compostion of SiO2. The mol weight of SiO2 is 2 * 16 + 28 = 60 g/mol mols of SiO2 = 1.30 / 60 = 0.0217 mol. Number of O2 atoms = 2 * 0.0217 * 6.022 x 10^27 = 2.61 x 10^26
