The concentration of SO42-(aq) in a sample of river water can be
determined using a precipitation titration in which a salt of Ba2+(aq) is
the standard solution and BaSO4(s) is the precipitate formed. What is
the concentration of SO42-(aq) in a 46.1 mL sample if 7.00 mL of a
0.00100 M Ba2+(aq) solution is needed to precipitate all the SO42-(aq)
in the sample?

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.
