Number of oxygen atoms in 1.6 g = 1.6 x 6.02 x 10^23 = 1.603 x 10^22 atoms.
Further Explanation:
Solution:
Quartz has the formula SiO2
From the periodic table:
mass of oxygen = 16 grams
mass of silicon = 28.0855 grams
Mass of one mole of quarts = 28.0855 + 2(16)
= 60.0855 grams
Formula:
number of moles = mass / molar mass
number of moles = 1.6 / 60.0855
= 0.0266 moles
Each mole of quartz contains Avogadro's number of atoms.
So,
Number of oxygen atoms in 1.6 g = 1.6 x 6.02 x 10^23
= 1.603 x 10^22 atoms
Quartz:
Quartz is a mineral made out of silicon and oxygen particles in a persistent structure of SiO₄ silicon–oxygen tetrahedra, with every oxygen being shared between two tetrahedra, giving a general substance equation of SiO₂. Quartz is the second most bottomless mineral in Earth's mainland covering, behind feldspar.
quartz utilized for:
