1. The formula of the hydrate is FePO₄•4H₂O
2. The name of the hydrate is Iron(iii) phosphate tetrahydrate.
1. Determination of the formula of the hydrate
- H₂O = 32.3%
- FePO₄ = 67.7%
- Formula =?
The formula of the hydrate can be obtained as follow:
Divide by their molar mass
H₂O = 32.3 / 18 = 1.794
FePO₄ = 67.7 / 151 = 0.448
Divide by the smallest
H₂O = 1.794 / 0.448 = 4
FePO₄ = 0.448 / 0.448 = 1
Therefore, the formula of the hydrate is FePO₄•4H₂O
The name of the hydrate is Iron(iii) phosphate tetrahydrate

Explanation:
When an atom gains or lose electrons then the atom tends to attain a negative or positive charge. Thus, the ions become charged.
Whereas when an atom is neutral then the number of electrons equals the number of protons. But when an atom becomes charged then the ions have unequal number of protons and electrons.
For example, atomic number of sodium is 11 and when it loses one electron then it attains a positive charge. The equation is as follows.
Thus, we can conclude that ions must always have an unequal number of protons and electrons.
<u>Answer:</u> The concentration of comes out to be 0.16 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of comes out to be 0.1862 M.
