Determine the percent composition of all elements in enstatite, mgsio3, a mineral found in earth's crust.

Explanation:

Percentage of an element in a compound:

Mass of magnesium atom = 24 g/mol

Mass of silicon atom = 28 g/mol

Mass of oxygen atom = 16 g/mol

Molar mass of =24 g/mol+28 g/mol+3 × 16 g/mol=100 g/mol

Composition of all elements in enstatite,

Percentage of magnesium :

Percentage of silicon:

Percentage of oxygen:
