4 A In The Gravimetric Determination Of Sulfur As Barium Sulfate S Is Calculated From The Equation S Wt Baso4 X 1 (16.4 KiB) Viewed 35 times
4(a) In the gravimetric determination of sulfur as barium sulfate, % S is calculated from the equation % S= (wt BaSO4 x AW S MW BaSO4 x 100 wt sample Calculate the absolute and relative error in % S from the following data: = 1.4336 ± 0.0002 g wt BaSO4 = 655.4 ± 0.2 mg AW S = 32.064 ± 0.008 g AW O = 15.9994 ± 0.0003 g wt sample AW Ba = 137.34 ± 0.01 g
