In order to calculate the heat gained by the water in the calorimeter, the mass of the water must be determined. It will be calculated from the volumes of HCl and NaOH and the density of water, 1.00 g/mL. You should approximate that the density of the NaOH and HCl mixture is equal to the density of water. For each trial, calculate the mass of water in the calorimeter. Report your values to 3 significant figures.

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.
