calculate the concentration of silver nitrate in mol/L M x V =0.2 average Vw in ml of 2.23 2.26 2.43 MxVw = Mwx20 Mw=? mol/L chloride in water sample = mmol/L? =?g/L chloride in sample =?ppm chloride in water sample
weight of particluate on filter 0.0235g = 23mg/cigarette volume of air sucked through 32x50ml= 1600ml =1.6 l I cant figure how to do this concentration of particulate matter= ?mg/l = ? mg/m3 help appreciated
if a membrane filter from a cigarette weighs 0.0313g bfore sample has been drawn through and 0.0548g after what is the weight of particluate matter on filter in g and mg/cigarette ? Volume of air sucked through=32x50ml=?mL=?L concentration of particulate matter=?mg/L =? mg/m3 ...
calculate3 the concentrationof chloride in water sample Mw using this equation mol Ag+ = 1= MxVwx10-3 = MxVw mol Cl- 1 Mwx20.00x10-3 Mwx20 so M x Vw=Mw x20 or Mw= M x Vw 20 Mw= ? mol/L chloride in water sample= ? mmol/L Mw=? g/L chloride in water sample Mw=?ppm in water sample...
chemistry this is a big one
mol Ag+ =1 MxVx10-3 MxV mol Cl- =1 0.01x20.00x103-= 0.2 so MxV=0.2 o9r M=0.2 V M=? mol/L silver nitrate Please then volumes of silver nitrate required 2.23 2.26 2.43ml average Vw = ? ml
a 100ml solution of 0.01M sodium chloride has how many ppm (mg/L) please?
sorry 0.1 M NH4OH has pH 9.8 so I need the theoretical pH for 14 - 0.5(pKb-log [base])=? also 0.1 M HAc pH=2.5 theoretical pH 0.5 (pKa-log [acid])= ? Gratefull for help
