Question

How many grams of Ba(OH)2 will dissolve in 100g of water at 75 degree Celsius

Answer 1

Solubility is a function of temperature. But for this case solubility is not given at that certain temperature and it is somewhat difficult to find for certain datas. I would be using the solubility at 20 degrees celsius which is 1.85g/100g Water

.0185 g / g water = g barium hydroxide / 100 g

1.85 g of barium hydroxide can be dissolved in 100 g of water. 

Hope this could help. Have a nice day.

Answer 2

Solubility is the ability of the solute to dissolve with the solvent to form a solution. Barium hydroxide needed to be dissolved in 100 g water is 1.85g.

What is mass?

Mass is the quantity or the weight of the substance used in the reaction of the system.

At 20 degrees celsius, the solubility of the water is 1.85 gm per 100 gm.

If, 100 gm of water = 1.85 gm water

So, the mass of the $\rm Ba(OH)_{2}$  will be 1.85 gm.

Therefore, 1.85 gm of Barium hydroxide is the mass.
