And what if the molarity of naoh is only 1? then how to find the ph and poh.please answer back now cause this question has been write to us and now tomorrow our teacher will ask to show it to him.please answer back..
Well, look at the definitions of each quantity.... "Molarity"="Moles of solute"/"Volume of solution" "Molality"="Moles of solute"/"Kilograms of solvent" "Molality" is thus independent of temperature, whereas "molarity" changes slightly with temperature as the density of the solution changes. For dilute solutions, "molarity"-="molality". to a very good approximation.
Moles n solution: Calculate the molarity of a solution of NaOH made by dissolving 2moles of sodium hydroxide in water and making up to 250cm^3?

Here's one way to do it. > Example Concentrated hydrochloric acid is usually available at a concentration of 37.7% by mass. The density of the solution is 1.19 g/mL. What is its molar concentration? Solution Step 1. Calculate the mass of 1 L of solution. "Mass of solution" = 1000 color(red)(cancel(color(black)("mL soln"))) × "1.19 g soln" /(1color(red)(cancel(color(black)("mL soln ...
Titration affects molarity by changing the volume of the solution. For example, if you have a 1M solution of NaOH in 1 Liter, then you have 1M Na+ ions. If you titrate this with 1M HCl, then it will take 1 Liter of HCl to fully titrate this. However, your Na+ ion concentration is now 1 mole in 2 liters, or 0.5M. So titrations generally increase volume and reduce molarities
