A titanium Bicycle frame displaces 0.314L of water as well as has a mass of 1.41kg. Explain what is the density of the titanium ing/cm3?
A certain atom has a threefold degenerate ground level, a non-degenerate electronically excited level at 3500 cm1, and a threefold degenerate level at 4700 cm?1. Calculate the partition function of these electronic states at 1900 K
A solution was prepared by dissolving 0.450 g MgSO4 (FW=120.363g/mol) in 0.500L of water. A 50.0 mL aliquot of this solution consumed 37.60 mL of EDTA solution in a titration.
