However, the theoretical yield and the actual yield is different which is 1.0 g and 0.88 g respectively. Ground calcium carbonate has many industrial. 1 mole CaCl2 equal to 1 mole CaCO3 so, 0.010 mole CaCl2----- 1 mole CaCO3 1 mole CaCl2. When CaCl2 is So, times 32.00 grams per mole of molecular oxygen. CO. 3 . Calcium carbonate is a white precipitate and insoluble in water. CaCO3molecularweight 100g/mol Na2CO3molecular weig. In a chemical reaction, the reactant that is consumed first and limits how much product can be formed is called the limiting reactant (or limiting reagent). plastics, paints and coatings industries, as a filler and as a coating pigment. The same is true of reactions. 2.50 g of CaCl2 is fully dissolved in a beaker of water and 2.50 g of Na2CO3 is fully dissolved in water in a second beaker. Therefore, you have more oxygen than required. 2. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. For example, suppose you begin with 40 grams of oxygen and 25 grams of glucose. So, times 32.00 grams per mole of molecular oxygen.
