The alcohol content of hard liquor is normally given in terms of the proof, which is defined as twice the percentage by volume of ethanol (C2 H5 OH )present. Calculatethe number of grams of alcohol present in 1.00L of 75 proof gin The density of ethanol is 0.798g/mL.
How many grams of dry NH4Cl need to be added to 2.10L of a 0.500 M solution of ammonia, , to prepare a buffer solution that has a of 8.84? Kb for ammonia is 1.8*10^-5.
if a molecule of a neon gas travels at an average of 400.m/s at a given temperature, estimates the average speed of a molucule of butane gas, C4H10, at the same temperature.
Find the lowest temperature of vaporization and the highest temperature when there is liquid left over and Determine the range of temperatures which could be used for this process.
