- How many moles of sodium hypochlorite can be prepared from 32.5 g of NaOH?arrow_forwardA chemist combined chloroform (CHCI,) and acetone (C, H,O) to create a solution where the mole fraction of chloroform, Xchloroform, is 0.187. The densities of chloroform and acetone are 1.48 g/mL and 0.791 g/mL, respectively. Calculate the molarity of the solution. Assume the volumes are additive. molarity: Calculate the molality of the solution. molality: marrow_forwardThe main constituents in vinegar are water and ethanoic acid (CH3COOH). In order to determine the concentration of acid in homemade vinegar, a student titrated 25 cm3 of 001 M NaOH against the vinegar. The equation for the reaction is: CH3COOH(aq) + NaOH(aq) ® CH3COONa(aq) + H2O(l) The following titration results were obtained: Burette readings (cm3) Rough 1 2 Final burette reading 20.10 38.90 31.40 Initial burette reading 0.10 20.00 12.50 Volume of vinegar used 20.00 18.90 18.90 (a) What volume of vinegar should be used in the calculation?
