On a bottle of iron supplement the facts list on the label states the following: ingredients: dried ferrous sulfate 202 mg (equivalent to 325 mg liquid ferrous sulfate which provides 65 mg elemental iron per tablet). use your knowledge of % composition of compounds to prove/ disprove the statement through calculation. (hint: how much iron is there in ferrous sulfate (a. k.a. iron (ii) sulfate? ) in the ferrous sulfate compound there are 0.376 parts iron and this calculation proves that the amounts of iron in the liquid and the solid form will be equivalent thus proving this statement. in the ferrous sulfate compound there are 0.376 parts iron. this knowledge can be used to multiply this number by the number of given mg of fe in the solid and liquid form. this does not equal 65 mg and thus the statement is disproved. in the calculation, the solid fe is equal to 74.3 mg and the liquid fe is equal to 119.47 fe and this proves the initial statement.
