DATA SHEET #2: DENSITY OF LIQUIDS                temp oC ______

Dair = 0.353/(273 + t) = ______________g/cm3         Dwater = _______________ g/cm3

Volume:  V = (Wair - Wwater)/(Dwater - Dair)   ;  Dwater - Dair = _______________ g/cm3

Determination of the Volume of the Glass Sample:

 A                Weight in Air (Wair,g) ________________ ________________ ________________ B        Weight in Water (Wwater,g) ________________ ________________ ________________ C         Buoyancy Effect (g) [A-B] ________________ ________________ ________________ D                    Volume (cm3) ________________ ________________ ________________ Average Volume: V = ______________ ± ____________  cm3

Density of a Liquid:     Dliquid = Dair + (Wair - Wliquid)/V
