5.00 grams of NaOH was dissolved in 750.0 mL of water which made a solution. To prepare 200 mL of 0.1 M NaOH, what volume of this solution would be needed to add to water?
The density of a 40 wt% solution of ethanol in water is 0.937 g/mL. The density of n-butanol is 0.810 g/mL. What is the concentration of n-butanol in ppm if you dissolve 25.0 μL of this alcohol in a 40 wt% solution of Ethanol in water. The final volume of the solution is 50.0 mL. Assume that the density of the ethanol solution does not change upon dissolution of the butanol. Use the correct number of significant figures! Hint: to...

What is the mass-volume percentage of a solution of 3.20g of ethanol dissolved in water to make 100.0mL of solution?
What is the partial molar volume of ethanol (in units of mL/mol) in a solution with water if 168 mL of ethanol is added to 650. mL of water and the volume increases by only 153 mL ? Take the density of ethanol to be 0.789 g/mL.
A) You have a stock solution of 15.8 M NH3. How many milliliters of this solution should you dilute to make 1500 mL of 0.300 M NH3? Express your answer using three significant figures. B) If you take a 11.5-mL portion of the stock solution and dilute it to a total volume of 0.550 L , what will be the concentration of the final solution? Express your answer using three significant figures.
Add 1.5 mL of the 1.0%(v/v) ethanol (mL) to 8.5 mL of deionized water. The ethanol standard in the test tube will have a final concentration of ____ %(v/v) ethanol? Add 1.0 mL of wine that has been diluted by a factor of 100, to a test tube and add 20 drops of sulfuric acid to it. The concentration of the diluted wine sample was found to be 0.23%(v/v) ethanol. Using the procedure stated, what was the original concentration of...
0.6573 g of potassium iodate is dissolved and diluted to a volume of 100.0 mL. Then 25.00 mL of this stock solution is pipetted into a 100.0 mL volumetric flask which is filled to the mark with water. What is the concentration of the final standard solution in mol/L? Include units in your answer, and round the final answer to the correct number of significant figures.
