Question

A sample of a mineral solid weighing 28.5 g was added to a graduated cylinder filled with to a level of 20.3 mL. As a result, the water level rose and the volume of the water with the mineral solid was 30. 5 mL. What is the density of the mineral

Answer 1

2.8 g/mL is the density of the mineral.

Step-by-step explanation:

The mass,
`m=28.5\ g`

Volume of the object = Volume of water level rose - Initial volume of water = 30.5 mL - 20.3 mL = 10.2 mL

The expression for the calculation of density is shown below as:-

`\rho=(m)/(V)`

`\rho=(28.5\ g)/(10.2 mL)=2.8\ g/mL`

2.8 g/mL is the density of the mineral.
