BaSO4 is insoluble in water so it is very weak electrolyte, ethanol can not produce ions so is non electrolyte other two are good electrolytes.
Calcium hydroxide.
The molecular weight of Ca(OH)2 (calcium hydroxide) is approximately 74.09 g/mol.
Calcium hydroxide is written as Ca(OH)2 because the hydroxide ion (OH-) is a polyatomic ion composed of one oxygen atom and one hydrogen atom. In the compound, there are two hydroxide ions associated with one calcium ion, which is why it is written as Ca(OH)2 and not CaOH2.
The products of the reaction between Na2CO3 (sodium carbonate) and Ca(OH)2 (calcium hydroxide) are NaOH (sodium hydroxide) and CaCO3 (calcium carbonate).
The solubility in water of calcium hydroxide: 1,73 g/L at 20 0C.
Nope... it is not.

Calcium hydroxide.
CaCl2 and H2O
In one mole of this solution, there are seven moles of H2O.
Ca(OH)2 and Na2O
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
