Question- 40 proof whiskey is diluted with water so that there is 4 mL whiskey and 96 mL water and then 10 mL whiskey and 90 mL water. what is the alcohol content of the 4 and 10% solutions?
Answer showing how to make each solution will get rated
Presume that we have a mixture of N2 (g) and O2 (g) of unknown composition whose total pressure is 385torr. If all the oxygen as is removed from the mixture by reaction with phosphorus, which doesn't react directly with nitrogen then the new press..
