Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Calculate the mass percent composition of iron for each iron ore: Fe2O3 (hematite), Fe3O4 (magnetite), FeCO3 (siderite). Express your answers using four significant figures. Enter your answers numerically separated by commas.
You can also calculate percent composition from a formula. This is similar to percent abundance in that what percentage of a compound is each element. If you look at the compound and tell how many of each element there is, you calculate the percent composition. Ex. Calculate the total mass of a compound just like before - CO2 C = 1 X 12 = 12g O = 2 X 16 = 32g 12+32 = 44g Then take the mass of each and divide by the total. 12/44 X100 = 27% carbon 32/44 X 100 = 73% oxygen CO2 is 27% carbon and 73% oxygen.
