A chemist adds 90.0 mL of a 0.049 molL potassium dichromate \( \left(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\right) \) solution to a reaction flask. Calculate the mass in grams of potassium dichromate the chemist has added to the flask. Be sure your answer has the correct number of significant digits.
