the mass does not change when immersed in water.
No matter how many times you post it.
A body has10kg in air and 6kg when immered in water. Calculate the density of the body

I think it means weight in kilograms,which is misleading and really incorrect physics. However many scales read in kilograms making the assumption that they will always be used on the surface of a planet where the acceleration of gravity, g, is about 9.81 m/s^2
Lets say it means
Weight in air = 10 g Newtons
Weight in water = 6 g Newtons
Therefore the weight of water displaced was 4 g Newtons
the mass density of water is about 1000 kg/ meter^3 so the weight density is about 1000 g Newtons/meter^3
so how many meters of water did we displace
Volume = 4 g Newtons /1000 g /m^3 = 0.004 meter^3
so the weight/volume = 10 g Newtons/ 0.004 m^3
2500 g Newtons / meter^3
divide by g to get mass / meter^3
so 2500 Kilograms / m^3
which is 2.5 grams / cm^3
