Bromine (Br) and mercury \( (\mathrm{Hg}) \) are the only two elements that occur as liquids at room temperature and pressure; the specific gravities of those liquids are \( 3.124 \) and \( 13.6 \) respectively. What is the combined mass of one gallon of mercury and one cup of bromine? \[ 1 b_{m} \] 1 U.S. gallon \( =4 \) quarts \( -8(16 \)-fl, oz \( ) \) pints \( -16 \) cups 1f. oz. of water has a mass of \( 29.574 \mathrm{~g} \)
