Question

a relative density bottle has a mass of 29.2 g when empty its mass is 116.2 g when it is full of liquid or diesel and when full of water it's mass is 129.2 g calculate the relative density of diesel​

Answer 1

0.87

Step-by-step explanation:

Given :

Mass of bottle = 29.2 g

Mass when filled with diesel = 116.2 g

Mass when filled with water = 129.2 g

The mass of water = (Mass when filled with water - mass of bottle)

Mass of water = 129.2 - 29.2 = 100 g

Mass of diesel = (Mass when filled with diesel - mass of bottle)

Mass of diesel = 116.2 - 29.2 = 87

Relative density of diesel = mass of diesel / mass of equal volume of water

Relative density = 87 / 100 = 0.87
