Question

) A silver ornament is suspected to be hollow. Its weight is 288.75 g and it can

displace 30 cubic cm of water. If specific gravity of silver is 10.5, find the volume of

cavity​

Answer 1

Answer:

2.5cc

Step-by-step explanation:

specific gravity = 10.5

hence, 10.5g silver displaces 1cc water

then, 1g silver displaces 1/10.5 cc water

then, 288.75g silver displaces 288.75/10.5 cc

= 27.5cc water.

but given, water displaced by silver ornament is 30cc

hence hollow cavity is 30-27.5 = 2.5cc
