Question

A vessel contains 30 mL of water. A sample of 5.0 g of copper metal is dropped into this vessel, raising the level of water in it to 40 mL. What is the density of the copper sample? Please show all steps leading to the final answer.

Answer 1

Actual volume=Final volume-initial volume=40-30=10mL

• Mass=5g

`\\ \rm\longmapsto Density=(Mass)/(Volume)`

`\\ \rm\longmapsto Density=(5)/(10)`

`\\ \rm\longmapsto Density=0.5g/ml`
