A piece of metal ore weighs 9.00 g.When a student places it into a graduated cylinder containing water,the liquid level rises from 21.25 mL to 26.47 mL.What is the density of the ore?
A) 0.340 g/mL
B) 0.580 g/mL
C) 1.72 g/mL
D) 2.94 g/mL

Density= mass/volume
First, we need to find the volume of the metal ore:
Volume of the metal ore = Final volume - Initial volume
Volume of the metal ore = 26.47 mL - 21.25 mL = 5.22 mL
Now, we can calculate the density of the metal ore:
Density= mass/volume
Density= 9.00 g / 5.22 mL = 1.721 g/mL (rounded to three significant figures)

Therefore, the best choice is C) 1.72 g/mL.
