One brand of commercial ferrous sulfate has 24.9% of the total molar mass coming from Fe. Given that the ferrous sulfate has a hydrated form i.e. has the general formula FeSO4.xH₂O, where x is the number of water molecules in the chemical formula, calculate the value of x in the commercial brand, quoting your answer to the nearest whole number. Show all your workings.

confused on this section please explain and give answer to each part 

thank you

a. Iron chlorosis causes plants to have a uniform yellowing of their leaves. Ferrous sulfate
is used to treat iron chlorosis.
One brand of commercial ferrous sulfate has 24.9 % of the total molar mass coming
from Fe. Given that the ferrous sulfate has a hydrated form i.e. has the general formula
FeSO4.xH₂O, where x is the number of water molecules in the chemical formula,
calculate the value of x in the commercial brand, quoting your answer to the nearest
whole number. Show all your workings.
II. During water treatment, the iron in the ferrate ion is reduced to Fe³+. This process
is described by the following half equation and standard electrode potential:
FeО²¯ (aq) +8H* (aq) +3e¯ ⇒ Fe³+ (aq) + 4H₂O (1); Ee =+
Use your answer to part (b)(i) to construct the balanced redox reaction, in acidic
conditions, for the reaction between FeО4²¯ and CH³ CH₂ CHO. Explain each
step in the process.
b. Compounds containing the ferrate ion (FeO,²-) have been proposed as
environmentally friendly water treatment chemicals as they are able oxidize and
degrade toxic organic compounds present in wastewater.
i. Construct a balanced half equation, in aqueous acidic conditions, for the oxidation
of the carbon atoms in CH3 CH₂ CHO to CO2. Explain each step of the process
and include state symbols.

iii. Given that the En for the redox reaction in part (b)(ii) is +1.46 V, calculate the
standard reduction potential for the process described in part (b)(1). You should
include your working in your TMA submission document.
