2.1.2.1) SG using pycnometer Easy 1
Total tried: Correct: Wrong:
A 50 mL pycnometer is found to weigh 119 g when empty, 173.06 g when filled with water, and 175.2224 g when filled with clove oil . Calculate the specific gravity of clove oil .

lb equals 1.04 kg
-
Weight of the empty pycnometer = 119 g.
Weight of the pycnometer containing water = 173.06 g.
Therefore, the weight water = 173.06 - 119 = 54.06 g.
Weight of the pycnometer containing clove oil = 175.2224 g.
Therefore, the weight of the clove oil alone = 175.2224 - 119 = 56.2224 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 56.2224 / 54.06 = 1.04
Thefore, the answer is 1.04 (no unit).
