Describe how we would prepare $250 \mathrm{mL}$ of $0.10 \mathrm{M}$ NaOH from solid $\mathrm{NaOH}$ and water.

To determine the massive sodium hydroxide that is present in 65 milliliters of a 2.25 Moeller solution. We'll take the mill leaders of the solution that we have and converted in the leaders. Then we recognize that polarity conservative conversion factor. And if it's 2.25 Moeller floating hydroxide, then for everyone. Leader, we have 2.25 moles, sodium hydroxide. Well, then take the mold sodium hydroxide and comforted two grams by multiplying by the molar mass sodium hydroxide, and we get 5.85 grams. Sodium hydroxide are present in 65 milliliters of a 2.25 Moeller sodium hydroxide solution.

In this problem. We're trying to determine the concentration of our So do my drugs, said Solution that we use 28.34 milliliters of 0.1085 Mueller hcl to neutralize. So first we should start by figuring out how many moles of hundreds and house we used to neutralize our solution and we can figure that out by multiplying our concentration. All right, this is molds for leader can multiply this by our volume used two yet the number of moles we used which is 0.0 zoo 30 or seven moles of hydrogen ions since there is a 1 to 1 ratio of hydrogen ions to each CEO. So if we use this many moles of hydrogen ions, we had that many moves of hydroxide ions in our solution. So you know that the concentration of our solution is equal to the concentration of hydroxide ions in our solution, because there's a 1 to 1 ratio which equals the number of moles we used over the volume we had which was 25 milliliters or 0.25 leaders. And this gives us a final concentration of 0.1230 Moeller

So we use a delusion equation here on this one. Also, if you want to make 500 mil, leaders have a point to Moller. Solution will take an unknown volume of the stock solution that is 15 Moeller. The unknown volume, when calculated, is 6.67 mil leaders. So I would take 6.67 mL of the 15 Mueller solution they looted to 500 mL and I would have a point to Mueller solution.
