A 6.8 g sample of metal pellets is placed into a graduated cylinder holding 7.1 ml of water. After the pellets are added, the water level stands at 9.30 ml. Determine the density of the pellets. (show all work)

I've tried 6.8 g / 9.30 ml and .97-.71 to get .24 but I'm pretty sure that's not anywhere in the ball park of the right answer.

density = mass/volume

mass = 6.8 g
volume = 9.30-7.1 = ?
Round the answer to two significant figures.

To determine the density of the metal pellets, you need to consider the change in volume after the pellets are added to the graduated cylinder.

The initial volume of the water in the graduated cylinder is 7.1 ml, and after the pellets are added, the final volume is 9.30 ml. The difference between the initial and final volumes gives you the volume of the pellets.

Volume of the pellets = Final volume - Initial volume
Volume of the pellets = 9.30 ml - 7.1 ml
Volume of the pellets = 2.20 ml

Next, you need to divide the mass of the pellets (6.8 g) by the volume of the pellets (2.20 ml) to find the density.

Density = Mass / Volume
Density = 6.8 g / 2.20 ml
Density ≈ 3.09 g/ml

So, the density of the metal pellets is approximately 3.09 g/ml.
