A certain mixture of gasoline obtained from a petroleum refinery plant was found to contain only isooctane (C8H18; FM = 114.22), methyl tert-butyl ether (C5H12O; FM = 88.15), and tetraethyl lead (C8H20Pb; FM = 323.4), a gasoline preservative. Upon complete combustion of 0.4582 g sample, it was found out that the mass of the CO2 (FM = 44.01) absorbent increases by 1.0702 g, while the mass of residue PbO (FM = 223.2) was determined to be 0.0964 g. From this data, calculate the following: a. % (w/w) C8H18b. % (w/w) C5H12Oc. % (w/w) C8H20Pbd. % (w/w) Pb (FM = 207.2) Answer a to c only

Vanadic ion, V3+, forms green salts and is a good reducingagent, being itself changed in neutral solutions to thenearly colorless ion V(OH)4+. Suppose that 15.0 mL of a0.200-M solution of vanadic sulfate, V2(SO4)3, was neededto reduce completely a 0.540-g sample of an unknownsubstance X. If each molecule of X accepted just oneelectron, what is the molecular weight of X? Suppose thateach molecule of X accepted three electrons; what wouldbe the molecular weight of X then?
