Given:
A piece of silver has a cavity inside it. The mass of silver in air is 367.5 gm. and that in water is 315 gm. If the density of silver is 10.5 gm/cc.
To Find:
What is the volume of cavity?
Solution:
Let us take:
Volume of silver = V cm³
Volume of cavity = u cm³
Mass of silver in air (M) = 367.5 gm
Volume of silver can be find out from this formula:
Volume of silver = V= 35 cm³
Volume of cavity can be find out from this formula:
...1)
From equation 1):
On simplify, we get:
u = 17.5 cm³
Means volume of cavity is 17.5 cm³
