Answer: 429 grams of 
should be added to 1.3 L of water to prepare 2.0 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n = moles of solute = 
= volume of solution in Liters
Now put all the given values in the formula of molarity, we get
Therefore, 429 grams of should be added to 1.3 L of water to prepare 2.0 M solution
Answer: Calcium sulfide is a chemical compound having formula CaS. While Calcium sulfide is inorganic compound g fomlaCaSO4.
Explanation:
calcium sulfide is use in preparation of hydrogen sulfide, luminous pain and as a depilatory in cosmetics while calcium sulfate is used as desiccant. calcium sulfides is white material crystallizes in cubes like rock salt while calcium sulfate has three different crystalized forms known as hemihydrate (CaSO4⋅12H2O) , anhydrate (CaSO4) and as gypsum (CaSO4⋅2H2O). hope this explanation will be helpful for you
