A mixture of Na2SO4 and its hydrate Na2SO4-10H2O has a mass of 1.5099 g. After heating to drive off all the water, the mass is only 1.1410 g. What is the weight percentage of Na2SO4•10H2O in the original mixture? Report your answer to 4 significant figures. Molar masses: Na,SO4 142.04 g/mol; Na,SO4•10H2O 322.19 g/mol. 3. MnCl2 reacts with AgNO3 in aqueous solutions to produce a precipitate of AgCl that can be filtered and weighed. The balanced equation for the reaction is: MnCl2 (aq) + 2 A£NO3 (aq) → 2 AgCl (s) + Mn(NO3)2 (aq) Suppose you have a mixture that contains MnCl2, plus other compounds that do not react with AgNO3. If 0.5159 g of the mixture yields 0.8715 g of AgCl, what is the percentage of MnCl2 in the mixture?…

O ADVANCED MATERIAL 三 Solving applied mass concentration problems In 1993 the Minnesota Department of Health set a health risk limit for 1,2-dibromoethane in groundwater of 4.00 ng/L. Suppose an analytical chemist recelves a sample of groundwater with a measured volume of 78.0 mL. Calculate the maximum mass in micrograms of 1,2- dibromoethane which the chemist could measure in this sample and still certify that the groundwater from which it came met Minnesota Department of Health standards.
