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
1.25

Vysvětlení
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
= 9.6
mass of H2O = 27.2 - 15.2
= 12
R.d = \(\frac{9.6}{12}\) = 0.8
