@X@user.full_name@X@ @GMU: A mixture containing an initial concentration of 0.1663 M for H2 and 0.1328 M for I2 is allowed to come to equilibrium (see reaction below). What must be the equilibrium concentration of HI?H2(g) + I2(g) → 2HI(g) Kc = 48.7000

@X@user.full_name@X@ @GMU: Determine the mole fraction of toluene if 7.1397 g of toluene, C7H8, was mixed with 6.86 g of benzene, C6H6. MW(C7H8) = 92.141 g/mol; MW(C6H6) = 78.114 g/mol.

@X@user.full_name@X@ @GMU: Determine the mole fraction of cyclohexene if 5.8539 g of cyclohexene, C6H10, was mixed with 6.02 g of cyclopentene, C5H8. MW(C6H10) = 82.145 g/mol; MW(C5H8) = 68.119 g/mol.

@X@user.full_name@X@ @GMU: What is the molality of a solution made by combining 3.8135 g rubidium chloride, RbCl, with 0.3072 L of water (assume a density of 1.00 g/mL)? The molecular weight is 120.9205 g/mol.

@X@user.full_name@X@ @GMU: Initially there were equilibrium concentrations of 0.1859 M A, 0.3333 M B, and 0.1859 M C (see reaction below). The concentration of C was suddenly increased to 11.73 M. What was the approximate concentration of each after equilibrium had been re-established?5A → 3 B +3 C Kc = 1.073
