Solubility Constant Conversion - Step by Step Guide

Click For Summary
SUMMARY

The discussion focuses on converting solubility constants from one unit to another, specifically from [cm^3(STP) H2O]/[cm^3 polymer*atm] to (g H2O/cm^3 polymer)/(g H2O/cm^3 air). The conditions for this conversion are set at 28 degrees Celsius, 70% relative humidity, and 1 atm pressure. The user, Wen Zhe, seeks a step-by-step guide to perform this conversion, indicating a need for clarity on the mathematical process involved.

PREREQUISITES
  • Understanding of solubility constants and their units
  • Basic knowledge of gas laws and STP (Standard Temperature and Pressure)
  • Familiarity with unit conversion techniques in chemistry
  • Proficiency in handling relative humidity effects on solubility
NEXT STEPS
  • Research the principles of solubility constants in polymer chemistry
  • Learn about the impact of temperature and humidity on solubility
  • Study unit conversion methods specific to chemical measurements
  • Explore examples of solubility calculations in peer-reviewed literature
USEFUL FOR

Chemists, polymer scientists, and students studying solubility and material properties will benefit from this discussion, particularly those involved in experimental design and data analysis related to polymer solubility.

Dear all,

It is stated in a literature that:

Solubility = [87 cm^3(STP) H20]/ [cm^3 polymer*atm] = 93,28 (g H20/cm^3 polymer)/ (g H20/cm^3 air)

where the storage conditions is 28 degress celsius and 70% relative humidity, at 1 atm.

My question, how do i convert from the first unit to the second? A step to step outline would be appreciated. I just can't get my head around this.

Many thanks,

Wen Zhe
