## Main Question or Discussion Point

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 celcius 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
