Web(2) Compound 1-1, dichloromethane and DIPEA (N,N-diisopropylethylamine) are mixed, and the volume of dichloromethane added per mole of compound 1-1 is 3.5L, and the moles of compound 1-1 and DIPEA The ratio is 1:6.5; after the reaction is heated to 0°C with magnetic stirring in an ice bath, MEM-Cl (2-methoxyethoxymethyl chloride) is added, and ... Webmoles = 0.16 M x 0.320 L = 0.0512 moles Therefore, there are 0.0512 moles of NaNO3 in the solution. b. Similarly, we can do this. First, we need to convert the volume from milliliters to liters: 244 mL = 0.244 L Then, we can put in the values: moles = 6.6 M x 0.244 L = 1.6104 moles Therefore, there are 1.6104 moles of HNO3 in the solution. c.

WebThe active agent in many hair bleaches is hydrogen peroxide. The amount of H2O2 in 14.6−g of hair bleach was determined by titration with a standard potassium permanganate solution: 2MnO4−(aq)+5H2O2(aq)+6H+(aq)→5O2(g)+2Mn2+(aq)+8H2O(l) (a) For the titration, how many moles of MnO4−were required if 31.1 mL of 0.193MKMnO4 was WebHint: The initial H2O2 solution is 3% m/v (mass/volume) hydrogen peroxide in water. That means that 3 g H2O2 are present in every 100 mL of solution. Hint: The molecular weight Answer the following. (So Confused!) How many moles of H 2 O 2 are present in Reactions 1 and 2?
