This is what I have so far but I don't know how to get the number of molecules within Benzoyl Peroxide? Benzoyl Peroxide aqueous Base, Acne Treatment Gel contains 10% of benzoyl peroxide (C14H10O4)

Molar mass of benzoyl peroxide is (2x14) + (1x10) + (16x4) = 168 + 10 + 64 = 242 g/mol

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Why is silver chloride is an ionic compound

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.
