I was wondering if anyone could help me answer this question? Try to explain it as best you can....

QN: A conductivity cell has plane parallel electrodes, each 2.2 cm x 2.2 cm in area, spaced 2.75 cm apart. When the cell is filled with an electrolyte, the measured conductance is found to be 2,849μS.

What is the conductivity of the solution?

How is resistance related to specific resistance?

what do you mean??? specific..

also i have another probelm..

Qn The molar conductances at infinite dillution, Ą, of aqueos solutions of the strong electrolyte sodium ethanoate, or sodium acetate as it is more commonly known, hydrochloric acid and sodium chloride are 9.10x10(-3), 42.5x10(-3) and 12.81x10(-3) S m(2squared) mol(-1) respectively at 25.0 C degrees.

What is the molar conductance at infinite dilution of ethanoic acid?

All help greatly appreciated... thanks

Specific resistance, better known as resistivity. Sorry for the confusion.

Resistance depends on the geometry of the cell and on the solution resistivity. Compare http://en.wikipedia.org/wiki/Electrical_resistance

Molar conductances of salts are sums of individual conductances of anions and cations. Check if you can't combine given values so that conductances from ions that you are not interested in cancel out.
