How exactly do you get pH from Ka?
The first one was correct! I just used the incorrect number of sig figs. Thank you so much!
Okay. I'll try both. 825mL - 712= 113. You have to convert mL to L in order to use the PV = nRT correct? if so,113mL=.113L P(.1130) = 1.47 moles CO2 * .0821 * 303 K .1130P=36.57 P = 323.6 atm -OR- 825-85.4 = 739.6 mL = .7396L .7369P=1.47(.0821)(303)
I'm still not sure which volume to use though. would it be 825 mL, 825mL - 85.4 mL, or 712 mL?
Sorry, I made a mistake. 85.4 mL = .0854 L. .0854 L * .79 g/cm3 = .0675g. .0675/46(MM of C2H5OH) = .0147 moles ethanol. .0147 moles ethanol = .0147 moles CO2.
I found the moles of CO2 and I got 1.47. 85.4 L ethanol * .79 g/cm3 = 67.5g ethanol. 67.5/(12+12+5+16+1)= 1.47 moles ethanol. 1.47 moles C2H5OH *(2 moles C2H5OH/ 2 moles CO2) = 1.47 moles CO2. What do I use for the volume? do I use the volume of the
