Question

An empty density bottle of capacity 50 ml weighs 27 g. When completely filled with
glycerine, it weighs 92 g. Calculate the density of glycerine. Express your answer in S.I.
units.

Answer 1

Answer:

Heya folk !!

Here's the answer you are looking for

☛ 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.
