A stock solution was prepared by dissolving approximately 0.4000 g of pure ASA in approximately 10 mL of NaOH(aq) and heating the solution to a gentle boil. After cooling to room temperature, the solution was poured into a 250-mL volumetric flask and diluted to the mark with DI water. Calculate the final concentration of this stock solution (after dilution).

How many grams of mgbr2 are needed to produce 75g or metal?

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
