If 10.1 g of CaCl2 is added to 200.g of water, calculate the mass percent of...
When 1.00 g of CaCl2 is added to 50.0 g of water in a coffee-cup calorimeter, it dissolves according to the following eqn: CaCl2 (s) Ca2 (aq) + 2Cl (aq) The temperature of the solution rises from 25.00°C to 28.51 °C. Assuming that all the heat flow involved in the reaction is transferred to the water, calculate q Also, assume that the csoln is equal to cwater Which is 4.18 J/g °C
How much water must be added to 40.0 g of CaCl2 to produce a solution that is 35.0 wt% CaCl2?
400 g NaCl and 800 g CaCl2 are added to water. 153g if NaCl are now in solution and 651 g of CaCl2 are in solution. if we now add an undetermined amount of Ca(NO3)2 to the solution, how do we go about seeing if the nitrate and sodium may precipitate another salt?
Answer the following solution concentration questions How much water must be added to 40.0 g of CaCl, to produce a solution thatis 35.0% CaCl2? a. b. You can purchase hydrochloric acid in a concentrated form that is 36.0 % HCl by mass and that has a density of 1.20 g/mL. Describe exactly how to prepare 1.15 L of 0.500 M HCI from the concentrated solution
CaCl (s) is highly soluble in water. Thus, when 10FW of CaCl2 (s) are added to a liter of water at 25C/1 atm, all of the solid will dissolve. Determine how much PbClh (s) will dissolve per liter of this solution? Assume that CaCl2 and PbCl2 dissolve as simple salts. that is, neglect species like CaOH and PbOH. Neglect activity corrections, and neglect volume changes due to the dissolution of the PbCl2 (s)
What mass of water must be used to prepare a solution of 25.5 g of CaCl2 dissolved in water if the mole fraction of the CaCl2 in solution is 0.105?
Suppose a 12.42g mixture of NaCl and CaCl2 is dissolved in water. To this solution, an excess of AgNO3 solution is added resulting in the formation of 31.12g of the precipitate. Calculate the % by mass of NaCl and CaCl2 in the original mixture. Show all work.
How many grams of CaCl2 are needed to make 5926 g of a solution that is 28.0% (m/m) calcium chloride in water? Note that mass is not technically the same thing as weight, but % (m/m) has the same meaning as % (w/w). Number g CaCl How many grams of water are needed to make this solution? Number g H20
Calculate the mass-mass percent concentration of a solution containing 300. g of water and 37.50 g of NaCl. Please, include the proper number of significant figures.
מו Calculate the mass of glucose (C6H606) that must be added to 100 g of water to give a solution whose freezing point is -3.8°C. The freezing point depression constant of water is 1.86 °C/m. The molar mass of glucose is 180.16 g/mol Give your answer in grams to 3 significant figures
