If a student prepares a solution of carbonate-free NaOH. Ahead performing a rough titration, the student discovers the concentration to be 0.0497 M instead of 0.1000 M. presuming that the volume of the solution is 950.0 mL, explain how many grams of sodium hydroxide should be added to the solution to produce a concentration as close as possible the desired 0.1000 M? Presume that the sodium hydroxide is carbonate-free
What volume (mL) of a concentrated solution of NaOH (6.00 M) must be diluted to 200. mL to make a 0.88 M NaOH solution
Using the quantities given in the Procedure, calculate the theoretical yields for the mononitration of (a) acetanilide and (b) methyl benzoate. Acetanilide = quantity is .5 g and molar mass 135.17 g/mol. methyl benzoate= quantity is .55g. and mola..
