Saccharin has the formula C7H5NO3S. Suppose you have a sample of a saccharin-containing sweetener with a mass of 2134 g. After decomposition to free the sulfur, S, and convert it to the sulfate ion, SO42-, the sulfate ion is then trapped as water insoluble BaSO4. The mass of the BaSO4 is 2071 g.
Ba2+(aq) + SO42- â BaSO4(s)
How many moles of SO42- ions are in the sample of BaSO4(s)?
Molar masses (g mol-1): S = 32.06, C7H5NO3S = 183.2, BaSO4 = 233.4
