ALEKS: Calculating the mass of a gas collected over water

[@JackieChan-x7r]

okay,so what is the pressure of CO2? and how did you get the number of 0.927?

[@RoxiHulet]

The pressure of CO2 is calculated starting at about 4:40. It is 0.927 atm, and it is calculated using Dalton's Law, which says the Ptotal = Pco2 + Ph2o

Thank you so much, I actually understand how to do this now!

[@RoxiHulet]

Nice! 😀

[@ethanstewart9970]

where did you get .08206 from?

[@RoxiHulet]

That is the value of the ideal gas constant, R.

[@JackieChan-x7r]

and how did you convert torr to atm, because you did not say

[@RoxiHulet]

The conversion factor between torr and atm is: 1 atm = 760 torr
