bonufazy [111]

Answer:

2.8 g/mL is the density of the mineral.

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=\frac{m}{V}

\rho=\frac{28.5\ g}{10.2 mL}=2.8\ g/mL

<u>2.8 g/mL is the density of the mineral.</u>
