Question

An empty specific gravity bottle weighs 32 g in a physical balance. When it is completely filled with water ,it has a mass of 72 g on filling it with methanol, The mass of the bottle is found to be 64 g. Calculate the relative density of methanol.​

Answer 1

Answer:

An empty specific gravity bottle weighs 32 g in a physical balance. When it is completely filled with water ,it has a mass of 72 g on filling it with methanol, The mass of the bottle is found to be 64 g. Calculate the relative density of methanol.

Answer 2

Step-by-step explanation:

Given,

1. Mass of RD bottle = 32g ( M1)
2. Mass of RD bottle+ water = 72g (M2)
3. Mass of RD bottle+methanol = 64g (M3)

RD of methanol = ?

R.D = (M3 -M1) /(M2-M1)

= (64 -32 ) / (72 - 32)

= 32/40

=0.8

• R.D of methanol is 0.8
