One method for measuring the alcohol content of a liquid is to titrate the ethanol (C2H5OH) with chromate (CrO4^2-). These reagents react to become Co2 and Cr^+3 respectively. Write the balanced equation for this redoc process under acidic conditions. If a 1.86g sample of an alcoholic beverage is titrated with 25.93 mL of 0.250 M sodium chromate, what is the percent by mass of alcohol in this beverage?
