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。

Molarity : The molarity of solution is a quantitative measure of concentration that is used to calculate the amount of solute dissolved per liter of solution. The number of moles of solute is the ratio of the mass of the solute to its molar mass. It is 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...
A 25.0 sample of HCl is neutralize by 26.5mL of 0.155 M NaOH. Calculate the molarity of the HCl solution. (Hint: In this case, Molarity of HCl is MA in moles/liter of HCl.)The equation would be M1V1/M2V2(0.155M)(26.5mL)/(25.0mL)=.164M Is this right?Do I multiply my answer ...
