You need to dissolve CaCl2 in water to make a mixture that is 39.5% calcium chloride by mass. If the total mass of the mixture is 113.0 g, what masses of CaCl2 and water should be used? Mass of CaCl2 Mass of water
CaCl2 --> 39.5% by mass
total mass = 113 g
so..
39.5/100 * 113 = 44.635 g of CaCl2
so..
mass of water = 113-44.635 = 68.365 g of water

Glucose has a molecular weight of 180 g/mole, sucrose 342 g/mole, and calcium chloride (CaCl2) 111. If we dissolve 18 g of glucose, 34 g of sucrose, and 11 g CaCl2 in 1 kg of water, what will the resulting solution’s osmolarity be? Be describe you methods in your response.
A 0.5 gram sample of calcium chloride dihydrate (CaCl2 • 2H2O) is heated driving off the water. The dehydrated calcium chloride (CaCl2) weighs 0.38 grams. What was the % H2O by mass? Hint: Just use grams, there is absolutely no need for moles this time. It is not a trick question.
25.0 grams of calcium chloride are allowed to dissolve in 100.0mL in an insulated styrofoam calorimeter. The temperature of the water before calcium chloride is added is 22.0 degrees celsius. After dissolving, the maximum temperature of the solution is 73.6 degrees celsius. a) Calculate the heat absorbed by the water. b) Is this q(p) or q(v)? c) Calculate deltaH for the reaction CaCl2(s) yields CaCl2(aq) (units should be kJ per mole.) d) Is deltaH any different from deltaE for this...
When 23.6 g of calcium chloride, CaCl2, was dissolved in water in a constant-pressure calorimeter, the temperature rose from 25.0 C to 38.7 C. If the heat capacity of the solution and the calorimeter is 1258 J/C, what is the enthalpy change when 0.710 mol of calcium chloride dissolves in water? The solution process is CaCl2(s) --> Ca2+(aq) + 2Cl–(aq)
You placed a sample of a hydrate of calcium chloride (CaCl2) in a weighed test tube, and weighed the filled test tube Then you heated it until no more water was evolved. After cooling, you weighed the test tube again. Mass of empty tube (g) 13.89 Mass of filled tube before heating (g) 18.55 Mass after cooling (g) 16.9 Calculate the following: Moles of anhydrous CaC12
