...but i did it a different way. i looked at an example in the textbook, but still don't really understand what i did. for P, i calculated 0.993 atm for n, i calculated 0.040 mol CO2 for T, i calculated 299.5 K then, i calculated 0.040 mol CO2 x 44.01g/1 mol CO2 = 1.76 g C...
chemistry ** CAN YOU LOOK AT MY ANSWER, PLEASE, DRBOB222? :)
the answer i came up w/ is 1.76g/L. is this correct?
if i'm using PV=nRT, and manipulate that formula to V=nRT/P to find the volume, do i use 44.01g as my molar mass of CO2 and convert that to moles to find 'n'? i'm really confused how to do this b/c it's not at STP.
