On a beach trip during spring break, you notice a silver chain in the sand next to your towel. Luckily you have an analytical balance, a graduated cylinder, and a bottle of water that you can use to verify the identity of the metal based on its density. You just so happen to remember that the density of silver is 0.01049 kg/cm3 from your chemistry class. If you begin with 6.15 mL of water in the graduated cylinder and the chain has a mass of 6,113.1 mg, what should be the final volume in the graduated cylinder after you drop the chain in it?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
