lb equals 1.04 kg
-
Weight of the empty pycnometer = 103 g.
Weight of the pycnometer containing water = 132.38 g.
Therefore, the weight water = 132.38 - 103 = 29.38 g.
Weight of the pycnometer containing clove oil = 133.5552 g.
Therefore, the weight of the clove oil alone = 133.5552 - 103 = 30.5552 g.
The specific gravity of clove oil will be the ratio of the weight of clove oil and the weight of water. Therefore, the SG is 30.5552 / 29.38 = 1.04
Thefore, the answer is 1.04 (no unit).
