It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration). Write an
aev [14]

Answer:

MnSO4.5H2O(s) ---------> MnSO4(s) + 5H2O(g)

Explanation:

The dehydration of a hydrate implies that the water of crystallization is lost. Water of crystallization is included in the crystal structure as it is formed and is incorporated into the structure of the compound.

Now the equation for the dehydration of manganese(II) sulfate pentahydrate is;

MnSO4.5H2O(s) ---------> MnSO4(s) + 5H2O(g)

The  MnSO4 is now said to be anhydrous.

Determine the mass of SO₂ that contains 6.075 × 10^26 S atoms.​
kondor19780726 [428]

Answer:

= 64584.7176 g

or

= 64.5847 kg

Explanation:

From our question, we have been asked to find the mass of SO₂ containing 6.075 × 10^26 S atoms.

We know that from Avogadro's constant,

1 mole of a substance contains 6.02 x 10²³ ions/atoms/units

Thus,

1 mole => 6.02 x 10²³ atoms

x moles=> 6.075 × 10²⁶ atoms

We cross multiply;

x moles = (6.075 × 10²⁶ x 1)/(6.02 x 10²³)

= 1009.1362 moles

1 mole of SO2 = 64 g

1009.1362 moles = ?

=>

\frac{1009.1362 \times 64}{1}

= 64584.7176 g

= 64.5847 kg
