An experiment calls for 50.0 of benzoyl chloride to be used (density=1.212 g/mL). What volume of benzoyl chloride is needed?
An aqueous solution of nitric acid has a density of 1.41 g/mL and contains 70.0% HNO3 by weight (wt/wt). What is the molarity of this solution?© BrainMass Inc. brainmass.com October 10, 2019, 7:37 am ad1c9bdddf
1. Volume, V = 20 mL
density, d = 0.8668 g/mL
Hence, mass of toluene, m = volume * density = V*d = 20*0.8668 = 17.336 g
molecular weight of toluene, M = 92.139 g/mol
Hence, number of moles involved in reaction = mass/molecular wt = ...
