What percent of FeSO_(4)cdot 6H_(2)O is Fe? 55.68% 12.68% 21.48% 29.89%

Question

Answer 1

To determine the percentage of iron (Fe) in

, we need to calculate the molar mass of the compound and then find the proportion of iron in it.First, let's calculate the molar mass of

:- Molar mass of Fe: 55.85 g/mol- Molar mass of S: 32.07 g/mol- Molar mass of O: 16.00 g/mol- Molar mass of H: 1.01 g/molThe molar mass of

is calculated as follows:

Next, we calculate the molar mass of

:

Now, we add the molar masses of

and

to get the molar mass of

:

Finally, we calculate the percentage of iron in

:

Therefore, the correct answer is:
