2K₂Cr₂O₇ (aq) + 8H₂SO₄ (aq) + 3C₂H₅OH (aq) --> 2C₂2(SO₄)₃ (aq) + 2K₂SO₄(aq) + 3CH₃COOH (aq) + 11H₂O (l)

The above reaction is what occurs in a breathalyzer test. The ethanol (MM = 46.08 g/mol) reacts with the dichromate ion in potassium dichromate (MM = 294.20 g/mol) to produce the green chromate ion in chromium sulfate (MM = 392.21 g/mol). The sample is analyzed in a hand-held spectrophotometer, and the amount of light transmitted is converted into an electrical signal. The signal is then converted to an absorbance value which is proportional to the amount of ethanol in a sample.

Calculate the grams of chromium sulfate formed from 0.0250 g ethanol.
