8. (12 points) 0.61 grams of a sample containing only Na2SO4 (142 g/mol) and K2SO4 (174 g/mol) is taken and dissolved in pure water. The sulfate is precipitated as barium sulfate and brought to a constant weight. The amount of BaSO4 (233 g/mol) obtained is found as 0.913 grams. What are the amounts of Na2SO4 and K2SO4 in grams in the mixture, respectively? (S=32 g/mol, O=16 g/mol) a) 0.20 and 0.41 b) 0.24 and 0.37 c) 0.27 and 0.34 d) 0.32 and 0.29 e) 0.38 and 0.23
