The distribution coefficient, Ko (Cether/Caster), for an organic substance X at room temperature is 10. What relative volume of ether to water should be used for the extraction of 90 percent of X from a water solution in a single extraction?

a police officer and a ambulance

answerca air mass;

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
