6.349 g mass of anhydrous magnesium sulfate will remain.
<h3>What are moles?</h3>A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Molar mass MgSO₄.7 H₂O = 246.52 g/mol
0.0527 moles
Molar mass MgSO₄ = 120.4 g/mol
Mass of anhydrous magnesium sulfate :
( 0.0527 x 120.4 ) => 6.349 g

<u>Answer:</u> The for the reaction is 54.425 kJ/mol
<u>Explanation:</u>
For the given balanced chemical equation:
We are given:
To calculate for the reaction, we use the equation:
For the given equation:
Putting values in above equation, we get:
Conversion factor used = 1 kJ = 1000 J
The expression of for the given reaction:
We are given:
Putting values in above equation, we get:
To calculate the gibbs free energy of the reaction, we use the equation:
where,
= Gibbs' free energy of the reaction = ?
= Standard gibbs' free energy change of the reaction = 46900 J
R = Gas constant =
T = Temperature =
= equilibrium constant in terms of partial pressure = 20.85
Putting values in above equation, we get:
Hence, the for the reaction is 54.425 kJ/mol
