[QUOTE="Karol, post: 4971700, member: 20512"] [h2]Homework Statement [/h2] Room temperature is 20[SUP]0[/SUP]C and relative humidity is 60%. what is the absolute moisture [h2]Homework Equations[/h2] Vapor pressure at 20[SUP]0[/SUP]C=17.5[atm] PV=nRT Molecular weight of water=18[gr/mol] [h2]The Attempt at a Solution[/h2] The vapor pressure at 20[SUP]0[/SUP]C: $$\frac{x}{17.5}=0.6\rightarrow x=10.5[atm]$$ $$PV=nRT\rightarrow 10.5\cdot 1=n\cdot 0.08208\cdot 293\rightarrow n=0.437[mol]$$ $$0.437\cdot 18=7.86[\frac{gr}{m^3}]$$ It should be 10[gr/m[SUP]3[/SUP]] [/QUOTE]
