Take the mass of the water lost and divide that number by the mass of hydrated calcium sulftate. Then multiply your answer by 100. For example:
To find the amount of water, subtract the mass of the anhydrous sample from the hydated one like this:
Mass of hydrated salt: 21.626
Mass of anhydrous salt: 21.441
21.626 - 21.441 = 0.185 (amount of water)
To find the percentage of water, divide the water mass by the hydrated mass number:
.185/21.626 = 0.00855
Now all you need to do is multiply your answer by 100 to get the percentage:
0.00855(100) = .8554%
To see this last part algebraically, you can say, "what percent of the hydrated salt (21.626) is the mass of water (0.185)?"
This would look like: x%(21.626)=0.185
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
The chemical reaction between water and calcium sulfate (CaSO4) results in the formation of calcium sulfate dihydrate (CaSO4·2H2O), commonly known as gypsum. This reaction is exothermic and reversible, meaning that when gypsum is dissolved in water, it can eventually revert back to calcium sulfate and water.
No. Gypsum is a calcium sulfate dihydrate.
The chemical formula for Calcium Sulfate is CaSO4
When barium sulfate is mixed with calcium chloride, a double displacement reaction occurs where barium chloride and calcium sulfate are formed. Barium chloride is soluble in water, while calcium sulfate is not, so a solid precipitate of calcium sulfate will form.
Gypsum is a hydrated calcium sulfate: CaSO4.2H2O.
No, calcium sulfate and calcium sulphate are the same chemical compound, commonly known as gypsum. Calcium sulfate dihydrate specifically refers to the hydrated form of calcium sulfate, where each molecule contains two molecules of water (CaSO4 ∙ 2H2O).
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
Gypsum, common mineral consisting of hydrated calcium sulfate (CaSO4·2H2O).
The anagram is "gypsum" (hydrated calcium sulfate).
The likely word is gypsum (hydrated calcium sulfate), a constituent of construction drywall.

No. Gypsum is a calcium sulfate dihydrate.
The product of iron sulfate reacting with calcium carbonate is iron carbonate and calcium sulfate. The iron from the iron sulfate displaces the calcium in the calcium carbonate to form iron carbonate, while the sulfate from the iron sulfate combines with the calcium to form calcium sulfate.
CaSO4, calcium sulfate, is sold under various names depending on what it's being used for. In one form it is called 'gypsum' (but that's a generic term, not a brand name). As a laboratory dessicant (drying agent) it is sold under the brand name Drierite.
No, calcium sulfate is not a base. It is a salt composed of calcium ions and sulfate ions.
No, calcium sulfate and lime are not the same product. Calcium sulfate is a compound containing calcium, sulfur, and oxygen, while lime typically refers to calcium oxide or calcium hydroxide, which are compounds containing calcium and oxygen. They have different chemical compositions and applications.
