Where is forsterite found?
Most gem grade forsterite comes from volcanic basalts, but the gem gravels of Mogok, Myanmar (formerly known as Burma) are thought to have weathered out of peridot-containing metamorphosed marbles. Forsterite is also found in many iron-nickel meteorites.
What is the difference between fayalite and forsterite?
Fayalite is the iron rich member with a pure formula of Fe2SiO4. Forsterite is the magnesium rich member with a pure formula of Mg2SiO4. Otherwise they are difficult to distinguish and virtually all specimens of the two minerals contain both iron and magnesium.
How do you find the empirical formula?
Calculate the empirical formula.
- In any empirical formula problem you must first find the mass % of the elements in the compound.
- Then change the % to grams.
- Next, divide all the masses by their respective molar masses.
- Pick the smallest answer of moles and divide all figures by that.
What is the name of sodium and magnesium?
Sodium magnesium sulfate is a double sulfate of sodium and magnesium. There are a number of different stoichiometries and degrees of hydration with different crystal structures, and many are minerals.
What is the empirical formula for MgO?
MgO
The Empirical Formula for magnesium oxide is MgO. Magnesium is a +2 cation and oxide is a -2 anion. Since the charges are equal and opposite these two ions will bond together in a 1 to 1 ratio of atoms.
How do you find the empirical formula of MgO?
Explanation:
- The ratio of atoms is the same as the ratio of moles.
- Mass of Mg = 0.297 g.
- Mass of magnesium oxide = mass of Mg + mass of O.
- 0.493 g = 0.297 g + mass of O.
- Mass of O = (0.493 – 0.297) g = 0.196 g.
- There is 1 mol of Mg for 1 mol of O .
- The empirical formula of magnesium oxide is MgO .
Where is wollastonite found?
Deposits of wollastonite have been found in Arizona, California, Idaho, Nevada, New Mexico, New York, and Utah. These deposits are typically skarns containing wollastonite as the major component and calcite, diopside, garnet, idocrase, and (or) quartz as minor components.
