What is the percent by mass of chlorine in Ca(ClO3)2? If the total mass of the mixture is 599.7 g, what masses of CaCl2 and water should be used? Calcium Chloride is a general purpose food additive, the anhydrous form being readily soluble in water with a solubility of 59 g in 100 ml of water at 0C. It finds an important application as an additive in plastics, fire extinguishers, blast furnaces and in wastewater treatment as a drainage aid. Solved Kemmi is practicing a calculation of the theoretical - Chegg WHITE,HARD ODORLESS FLAKE, What is the percent by mass of calcium in the compound? Calculate the molecular mass of calcium chloride (CaCl2). 38.765% B. {/eq}, its molar mass. If the total mass of the mixture is 278.6 g, what masses of CaCl_2 and water should be used? If the total mass of the mixture is 994.1 g, what masses of CaCl2 and water should be used? How can I calculate the percent composition of water in a hydrate? If the total mass of the mixture is 254.6 g, what masses of CaCl_2 and water should be used? \\ A 5% B 10% C 15% D 20% E 25 %. So that makes the weight of $\ce{CaCl2.6H2O}$ present in the intial mixture to be: Next, calculate the number of moles of $\ce{CaCl2.6H2O}$ you had in the beginning by: dividing the mass you've just obtained by the molecular mass of this compound. Answered: 2. (To make 100mL of 50mM CaCl2, weigh | bartleby You need to dissolve CaCl2 in water to make a mixture that is 33.5% calcium chloride by mass. CHEMISTRY 103: PERCENT WATER IN A HYDRATE - Louisiana Tech University moles CaCl2.2H2O to grams Molecular weight calculation: 40.078 + 35.453*2 + 2* (1.00794*2 + 15.9994) Percent composition by element Element: Chlorine Symbol: Cl Atomic Mass: 35.453 # of Atoms: 2 Mass Percent: 48.231% Element: Calcium Symbol: Ca Atomic Mass: 40.078 # of Atoms: 1 Mass Percent: 27.261% Element: Hydrogen Symbol: H Atomic Mass: 1.00794
