50,290,000 KM
50,290,000*1000= 5290000000 meters
Because it has high electrical conductivity
Answer: The density of kerosene is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g
Volume of kersone =
Putting in the values we get:
Thus the density of kerosene is
