The  Ph of the cell is = 7.4

Ph  = -log  (H^+  concentration)

Ph  =-  log ( 3.98 x10^-8)  =  7.4


this mean the cell is basic  since the PH>7

What would be the vapor pressure at 25.0 °c of a solution of 5.00 g of glucose (c6h12o6) in 100.0 g of ethanol (c2h5oh)?
Crank
Use Raoult's Law:
Psolution = (χsolvent) (P°solvent)

24.90 = (x) (25.756)

x = 0.966765 (this is the solvent mole fraction)

χsolute = 1 - 0.966765 = 0.033235

χsolute = 0.03324 (to four sig figs)
