Asolution contains 11% by mass of sodium chloride. this means that a. there are 11 g of sodium chloride in in 1.0 ml of this solution b. the density of the solution is 11 g/ml c. 100 g of the solution contains 11 g of sodium chloride d. the molality of the solution is 11 e. 100 ml of the solution contains 11 g of sodium chloride

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.
