Nitrogen gas is introduced into a large deflated plastic bag. no gas is allowed to escape, but as more and more nitrogen is added, the bag inflates to accommodate it. the pressure of the gas within the bag remains at 1.00 atm and its temperature remains at room temperature (20.0? c). how many moles n have been introduced into the bag by the time its volume reaches 22.4 l

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.
