How much volume in mL will you need to take from 4.3 M concentrated stock solution if you would like to prepare a diluted 0.6 solution with 100 mL?
2) 19.63 mL of 0.100 M NaOH is required to neutralize 2.00 mL of a solution containing acetic acid according to the following reaction: HC2H302(aq) + NaOH(aq) → NaC2H3O2(aq) + H2O(1). How many grams of acetic acid are present in 2 mL solution? Report the correct number of significant figures, and report the units. 3) 19.63 mL of 0.100 M NaOH is required to neutralize 2.00 mL of a solution containing acetic acid according to the following reaction: HC2H3O2(aq) +...
Question 12 (1 point) A 10.0 mL sample of a 10.80 M NaC1 solution is diluted to a final volume of 650.0 mL. What is the molarity of the final solution? 702.0 166.0 0.166 0.016
please show work 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...
Question 6 Using stock solutions to make up a solution: from final concentration to volume You need to digest a sample of DNA with a restriction enzyme. You will do this reaction later in the semester. The buffer for this reaction has a final concentration of 40 mM Tris, pH 7.5, 10 mM MgCl2 and 50 mM KCl. You have the following stock solutions: 0.5 M Tris, pH 7.5, 1 M MgCl2 and 2 M KCl. How would you make...
