You need to prepare 250.0 mL of a 1.10 M HCl solution from a 3.00 M HCl stock solution. Assuming that the accuracy of the concentration is important, which type of glassware should you use to make the solution?

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?
