"how many grams of sucrose (c12h22o11) are in 1.55 l of 0.758 m sucrose solution"
Ierofanga [76]
<span>You would use the equation: Molarity M equals amount of solution over volume of solution. So, 0.758 M equals x L divided by 1.55 L OR 0.758 M = x L / 1.55 L . To solve: 1.55 multiplied by 0.758 equals 1.1479. The answer is 1.1479.</span>

What is the overall cell potential for this redox reaction? Cd + Hg22+ → Cd2+ + 2Hg Given: Cd2+ + 2e− → Cd(s) = –0.40 and Hg22+
Hoochie [10]

Answer:  1.19 V

Explanation:

Standard potential for an electrochemical cell is given by:

E^0{cell} = standard electrode potential =E^0{cathode}-E^0{anode}

The E^0 values have to be reduction potentials.  

Given:

E^o_{Cd^{2+}/Cd}=-0.40V

E^o_{Hg_2^{2+}/Hg}=0.79V

Cd+Hg_2^{2+}\rightarrow Cd^{2+}+2Hg

Cadmium is losing electrons , undergo oxidation and thus act as anode. mercury is gaining electrons, undergo reduction and thus acts as cathode.

E^0{cell} = standard electrode potential =E^0{cathode}-E^0{anode}=0.79-(-0.40)=1.19V

Thus the standard potential for an electrochemical cell with the cell reaction is 1.19 V.
