if a glass contains 42 ml of water and 20 g metal object placed in the glass causes the water level to rise by 15 ml what is the density of the metal object?

First of all we will have to know the volume of the metal so (47-15) which is 27 so the metals volume is 27 ml
next we have to get the density
Density = mass / volume
so we will divide the mass which is 20g by the volume which is 27 ml, we get 0.7 g/cm3 which is the density of the metal
So basically
(Density of the metal is 0.7 g/cm3)

Dropping a dry bar of soap on the ground won’t clean it, by it will pick up germs from the ground so the soap would be dirty
