Question

The mass of an empty RD bottle is 580g.Whenever it is completely filled with water the mass is 1080g.and when it is completely filled with unknown liquid the mass is 1580 g. Find
1.The RD of the liquid
2.The capacity of the RD bottle
3.What is the density of the unknown liquid in SI unit?​

Answer 1

Answer:

The answer is 1994 kg/m³

Explanation:

The mass of filled water is =(1080-580)=500g

Density of water is 997 kg/m³=.997 g/cc

Volume of water is 500/.997=501.5cc

Hence the mass of unknown liquid=(1580-580)=1000 g

Volume of bottle is unchanged

Density of unknown liquid is= 1000/501.5 g/cc=

1.994 g/cc=1994 kg/m³(SI UNIT)

Answer 2

Answer:

1994kg/m²is a correct answer
