The half-life of the isotope Osmium-183 is 12 hours. Choose the equation below that gives the remaining mass of Osmium-183 in grams, Mn, after n half-lives have elapsed if there was an initial mass of 820 grams before decay. Then, use the equation to determine the mass remaining after 24 hours have passed.
