Question

a beaker of capacity 50 ml weighs 27g when empty and 90g when filled with glycerine in kg/m3. ​

Answer 1

☛ Mass of bottle = 30g

☛ Mass of bottle + mass of liquid = 53.4g

So, mass of liquid = (53.4 - 30)g = 23.4g

☛ Also, mass of bottle + mass of water = 48g

So, mass of water = (48 - 30)g = 18g

➡️We know

Let the density of the liquid be d.

And we know that density of water is 1g/cc

And volume of the bottle be V.

Since, both the liquid and water are filled in the same bottle,

volume of water = volume of liquid = V

So,

☛ Mass of liquid = Vd = 23.4g

☛Mass of water = V(1) = 18g

V = 18g/1g/cc =18cc

Thus,

Vd = 23.4g

18cc (d) = 23.4g

Therefore, density of the liquid is 1.3g/cc.
