For a titration experiment: I am using 1.025 M of NaOH(aq) as my titrant. My titration solution is 4.0 g of potassium hydrogen tartrate, with 300 mL of distilled water. After 4 trials, my average NaOH used was 1.680 mL. I am having problems figuring out how to calculate my findings. Each trial started with 50 mL of potassium hydrogen tartrate solution, and 2 drops of phenophthalein. Then I added 1.680 mL of NaOH (on average) to get titration to...

I have 3 questions, please show work so I can learn how to do the problems on my own. 1. An electric field E in N/C, right causes the m in grams ball in the figure to hang at a T degree angle. What is the charge on the ball in nanoCoulombs? 2. What is the magnetic flux through the loop shown in the figure? B=5.49 T, G=1.73 T and L=46.62 cm. 3. A straight wire carrying a current of...

so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...
