Determine the molarity of a solution of twenty grams of Ammonium bromide, NH4Br, in enough water to produce 132 mL of solution?
quininehydrochlorid (C20H24N2O2HCl) of 100 grams is transferred into a volume flask 100-mL with 5.00 mL of 1 M sulphuric acid and diluted with H2O. Then five mL of it gets transferred into a 500-mL volumetric flask where 25.0 mL of 1 M sulphuric acid is added H2O is then diluted to volume 1.00 mL gets transferred into a 100 mL volumetric flask after some time which is then being diluted to volume with 0.05 M sulphuric acid. Determine the concentration of quininehydrochlorid?
