Question

The mass of the density bottle is 50 g when empty, 75 g when full of water and 72 g when full of an oil.
Find a) capacity of density bottle, b) density of oil.

Answer 1

Answer:



Explanation:

Mass of an empty density bottle (M1)=50g

Mass of the bottle + Mass of the water=80g

Mass of the bottle+ Mass of the oil= 75 g

Mass of water=(M2-M1)g= 30g

Mass of oil =(M3-M1)g= 25g

Since the density of water is 1g/cm^3 , therefore capacity of density bottle V=30cm^3

Density of the oil=Mass of the oil/Volume of the oil= 25/30=0.83 g/cm^3

R.D of the oil is 0.83
