The molarity of C2O42- in a saturated solution of CdC2O4 was determined to be 0.000122 M. Calculate the solubility product constant (Ksp) for CdC2O4.
CdC2O4 (s) <----> Cd2+ (aq) + C2O42- (aq)
Molar Mass (g/mol)
CdC2O4 200.43
The total pressure in a flask containing air and ethanol at 257C is 878 mm Hg. The pressure of the air in the flask at 257C is 762 mm Hg. If the flask is immersed in a water bath at 350C
the red lice in the hydrogen spectrum is caused by the electron moving between which two energe levels? (the ionization energy of a hydroge atom is 2.18X10^-18J)
54.0 mL of a 1.40 M solution is diluted to a volume of 218 mL. A 109-mL portion of that solution is diluted using 183 mL of water. What is the final concentration.
