How many grams of each of the following substances will dissolve in 100 ml of cold water; ce(io3)4, raso4, (nh4)2seo4?

= 0.123g ,  = and = 96 g

Explanations: The question asks about the solubility of each of the compounds in grams per 100 mL of water. density of water is 1 gram per mL. So, 100 mL of water would be same as 100 g water.

In solubility charts, the solubilities are also shown in grams of compound per 100 grams of water.

Solubility of is 0.123 g, solubility of is 0.00021  g and the solubility of is 96 g per 100 g of water.

Since the question also asks about grams of each soluble in 100 mL that is 100 g of water, the grams of each salts will be same as their  above solubilities that is, is 0.123 g, is 0.00021  g and the solubility of is 96 g.
