New ads for the toyota Prius claim that it has saved over 1 billion gallons (2.8 x 10^9kg) of gasoline. Assuming that gasoline is 100% octane (C8H18) how much has the prius reduced emissions of carbon dioxide.
A solution of I- gives 301.0 mV in a cell with an iodide ion selective electrode. 10.0 mL of the solution is mixed with 3.00 mL of 1.00 x10^-6 M AgNO3, and the Ag is completely precipitated as AgI. The cell then gives 310.2 mV. Assume the electrod..
