Ok here is another one! Concentrated aqueous HClO4 has a concentration of 14.8 M. Calculate the concentrations of ALL ions present in a solution prepared by pipetting 5.00mL of concentrated HClO4 into a 1000.0-mL volumetric flask and filling to the mark. Also calculate the pH ...

250 milliliters = 0.25 L; To make a 3.0 M NaOH solution from 6.0 M NaOH, you need equal parts of water and NaOH solution You need 0.25 Liters of the solution, so you need 1/2 * 0.25 = 125 milliliters 6.0 M NaOH, and 125 milliliters water

Thanks. I can help with this. And the experiment part of my question meant that if an experiment I would need to know what you were doing. As you have written it the problem now makes sense. 2NaOH + H2SO4 ==> Na2SO4 + 2H2O First, how many moles NaOH do you have in the ...
