Question

Volume of density bottle is 20 mL. and mass of the density bottle is 50 g when it is empty. and mass of the density bottle filled with liquid-A is 125 g. and mass of the density bottle filled with liquid-B is 175 g. what is the relative density of the liquid-A with respect to liquid-B?​

Answer 1

Given : Volume of density bottle = 20 mL Mass of the empty density bottle = 50 g

Mass of the density bottle filled with liquid-A = 125 g

Mass of the density bottle filled with liquid-B = 175 g

To find : The relative density of liquid-A with respect to liquid-B

Solution : We know that,

• Density = mass/volume

• Mass of liquid-A only = 125 - 50 g = 75g

• Mass of liquid-B only = 175 - 50 g = 125g

• Relative density = mass of liquid-A olny / mass of liquid-B only

• Relative density = 75/125

= 3/5

= 0.6

So The relative density of the liquid-A with respect to liquid-B is 0.6.
