Calculate the molarity of a solution that contains 3.20 g of KCl in 150 mL of solution.Concentration of Solution:A solution is a type of mixture in which we don't really see the division between the components. It is as if the whole mixture just contains one comp...
An Example of How to Calculate Molarity Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. To ...
CALCULATE THE MOLARITY OF AN ACETIC ACID SOLUTION WHICH IS 2% IONISED, THE PKA OF ACETIC ACID IS 4.74 相关知识点: 试题来源: 解析 4.74是指醋酸在水中的电离程度,通过这个数可以算出醋酸根的电离浓度再除以2%应该是他的浓度吧。10的-4.74次幂除以2%就是他的浓度(M) 不知道对不对。

Calculate the molar solubility of a saturated solution of Ag2CO3. Ksp=8.1×10−12 ? Solubility Constant: The solubility of a solute in a solvent is the maximum number of moles of solute that can be dissolved in one liter of solution at a given temperature and pressure...
Calculate the molarity of a HCl solution if 34.21 mL of 0.0431 M NaOH neutralizes 25.00 mL of the acid solution. Calculate the molarity of the following solutions. - 60.5 g of HCl in 2.00 L of a HCl solution. - 34.5 g of NaOH in 400. mL of a...
Multiply the molarity of the solution by the number of ions formed when a single formula unit of the compound dissociates to find the osmolarity. CaCl2, for example, would dissociate in water to form three ions, while NaCl would form two. Consequently, a 1-molar solution of CaCl2 is a 3...
If you don't know the concentrations of your initial solutions, calculate molarity by dividing the number of moles in a solute by the volume of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this...
