Question

A density bottle wieghs 30 g when empty and 54g when filled with kerosene.Find density of kerosene in CGS units and its RD(volume of bottle is 30 ml)​

Answer 1

Answer:

The mass of the bottle is given as 30 g.

The mass of the liquid is given as 53.4 g - 30 g = 23.4 g.

The mass of water is given as 48 g - 30 g = 18 g = 0.018 kg.

The volume is calculated.

We know, Density = Mass / Volume.

As the mass of water is determined and the density of water is given, the volume of water is given as follows.

Volume = Mass / Density = 0.018 / 1000 = 18×10

−6

m

.

Now the density of the liquid is given as,

18×10

−6

m

23.4×10

−3

m

=1300kg/m

.

Hence, the density of the liquid is 1300kg/m
