Question

A metal piece weight 200 gf in air and 150 gf when completely immersed in water 1 calculate the relative density of the metal piece 2 how much will it weight in a liquid of density 0.8 g

Answer 1

pls mark on the brain list pls

Answer:(I). , (II).

Explanation:

Given that,

Weight of metal piece in air

Weight of metal piece in water

We know that,

Mass = Volume X Density

Weight in air ,

....(I)

Weight in water,

= upthrust force

We know that,

Upthrust of water =  apparent loss of weight of solid = weight in air - weight in liquid

We know that,

.....(II)

Now, volume of the solid

Now, divided equation (I) by (II)

(I). The relative density of the metal piece is

(II). The weight in liquid when density

Weight in liquid

Hence, this is the required solutions
