An unopened can of soda has an aqueous CO2 concentration of 0.21 M at 25.0
K = C/P , 3.4 x 10^-2 = 0.21 /P
P = 6.17 atm = 6.2 atm = 6.2 x 760 torr = 4.7 x 10^3 torr
hence A is answer

6.) The solubility of CO2 (g) in water is 3.2 x 102 M at 25.0 °C and 1.0 atm pressure. a.) What is the Henry's Law constant for CO2 (g)? Cg = k P, ; Cg = concentration in M; k = Henry's Law constant in mol L atm*'; P. = pressure in atm. 3.2 x 10-2 M=k (1.0 atm) (3.2 x 10-2 M)/(1.0 atm) = k = 3.2 x 10-2 M/atm = 3.2 x 10-2 mol L atm" b.)...

A soda pop has a pH = 3.80 at 25oC. Calculate the pressure of CO2 inside a closed-bottle of this soda pop at 25oC. Assume only water and CO2 are present and all dissolved CO2 is present as H2CO3. Ka,1(H2CO3) = 4.3 x 10-7 and ΔGfo(H2CO3,aq) = - 623.08 kJ/m Please include all math steps. The answer is Pco2=1.7atm
A Cu/Cu2+ concentration cell has a voltage of 0.21 V at 25 ∘C. The concentration of Cu2+ in one of the half-cells is 1.4×10−3 M . Part A What is the concentration of Cu2+ in the other half-cell? (Assume the concentration in the unknown cell to be the lower of the two concentrations.) Express your answer using two significant figures. [Cu2+] [Cu2+] = nothing M
