After so many years youre still the best THANJ YOU

how do we do this if they are asking for mass and moles

[@toddrenshaw24]

Your videos are saving me right now. On top of that I'm actually learning from this, not just struggling to muddle through. Thanks a lot!

[@RoxiHulet]

That's so awesome to hear! Thank you so much!

[@toddrenshaw24]

@@RoxiHulet I'll be using your content through my next several years of school. Top notch help!

how come we regularly just change celsius to kelvin by adding 273 but in here it's 273.15

[@RoxiHulet]

273 is 273.15 written to 3 significant figures. Sometimes ALEKS is picky about those last 2 digits.

[@RyanWilliamsBaromey]

Do you still use the same equation if it asks for temp or pressure

[@RoxiHulet]

Yes, this equation can be used if you are trying to solve for any of the gas variables - pressure, volume, temperature, or moles.

@@RoxiHulet thanks

[@italiaherrera4381]

does the pressure always need to be in atm?

[@RoxiHulet]

For this equation, yes it does.

Where did 0.08206 come from 👀

[@RoxiHulet]

Good question - that's the value of R, the gas constant.
