The mass of a specific gravity bottle is 15.2g when it is empty. it is 24.8g when filled with kerosene and 27.2g when filled with distilled water. Calculate the relative density of kerosene
A
1.25
B
1.10
C
0.90
D
0.80
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Masses of kerosene = 24.8 - 15.2
= 9.6
mass of H2O = 27.2 - 15.2
= 12
R.d = \(\frac{9.6}{12}\) = 0.8
