Answer 2

Iron Oxide 3 Paint Mass Calculation

The mass of iron oxide 3 can be calculated using the given values: 82, 64, 48, and 160.

The formula for iron oxide 3 is Fe2O3, which means it consists of two iron (Fe) atoms and three oxygen (O) atoms.

To calculate the molar mass of Fe2O3, we can use the atomic masses of iron (Fe) and oxygen (O) from the periodic table.

The atomic mass of iron (Fe) is approximately 55.845 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol.

Using these values, we can calculate the molar mass of Fe2O3:

Molar mass of Fe2O3: 2(Fe) + 3(O) = 2(55.845) + 3(16.00) = 111.69 + 48.00 = 159.69 g/mol

Therefore, the molar mass of iron oxide 3 (Fe2O3) is approximately 159.69 g/mol.

This calculation is based on the atomic masses of iron and oxygen, and it provides the molar mass of iron oxide 3 as approximately 159.69 g/mol.
