How many grams of SO2 can be produced if
2.5 moles of O2 are used?
S2 + 2O2 → 2SO2

mass of SO2 is 160 g

Explanation: according to equation number of moles of SO2

Is same as amount of Oxygen, also 2.5 moles.

Molar mass of SO2 is 32.07 +2·16 = 64.07 g/mol

Mass is m= nM = 2.5 mol· 64.07 g/mol= 160.175 g

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
