La solubilidad de un gas en agua es 0.22g-L a 20.0 Kpa. Calcule la solubilidad si la presión aumenta a 115Kpa.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa
