You need to use a dilute hydrochloric acid solution in an experiment. However, the only bottle of hydrochloric acid in your lab’s acid‑base cabinet is 8.0 M. Calculate the pH of the solution you prepare by diluting 1.5 mL of the 8.0 M HCl to a final volume of 250 mL with H2O. Use appropriate significant figures in your answer.

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?
