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 volume of 50 % by mass NaOH needed to prepare 1.0L of 0.1 M NaOH solution. What volume of a 1.7 M NaOH solution can be prepared from 74.5 mL of a 16.0 M NaOH solution? Calculate the molarity of the 50% of NaOH by volu...
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 molarity of the solution. Molarity is equal to the number of moles of solute divided by the number of liters of solvent, so divide the number of moles by the number of liters of solution to find the molarity. Step 3 Determine whether the solute dissociates as it dissolves....

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 ...
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 for both substances to let you calculate the final concentration of the solution. (Remember 1.33 M stands for 1.33 mol/L and not 1.3 moles...
