How many grams of CaSO4 (molar mass = 136.2 g/mol) can be produced from the reaction of 0.0126 mol CaBr2 with excess Li2SO4? What is the percent yield if 1.56g CaSO4, is produced?
CaBr2 + Li2SO4 --> CaSO4+ 2LiBr

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
