Weighing: Errors due to Buoyancy Buoyancy equation: a d d m 1 ' = o a w d d m 1 d a : density of air; d : density of weight; d w : density of weight; and d o : density of the objective. This formula need to be remembered !
Calculate buoyancy correction for water NaCl and AgNO Calculate buoyancy correction for water, NaCl and AgNO 3 . d is 8.0 g/mL; d t is 1.0 g/mL; d N Cl is 2.16 g/mL; w water NaCl and d AgNO3 is 4.45 g/mL
