Answer is: 4.826 grams of anhydrous nickel(II) sulfate could be obtained.

m(NiSO₄×7H₂O) = 8.753 g; mass of heptahydrate.

m(NiSO₄×6H₂O) = 8.192 g; mass of hexahydrate.

m(H₂O) = m(NiSO₄×7H₂O) - m(NiSO₄×6H₂O).

m(H₂O) = 8.753 g - 8.192 g.

m(H₂O) = 0.561 g.

m(NiSO₄) = m(NiSO₄×7H₂O) - 7 · m(H₂O).

m(NiSO₄) = 8.753 g - 7 · 0.561 g.

m(NiSO₄) = 4.826 g.

Ice is less dense than water. Hydrogen bonding makes water more dense than when it is in the form of ice!

Covalent solutes are considered non-electrolytes. What does this mean for the conductivity of the solution? A) Non-electrolytes
iogann1982 [59]

Electrolytes are those which dissociates in solution and produces ions.

Ions can carry current,so Electrolytes conduct electiricity.

And non electrolytes are those which do not dissociate in solution and doesnt produce ions.

Since non electrolytes do not produce ions they cannot conduct electricity.

<u>Hence the right option is:</u>

B) Non-electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
