The density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

<h3>How to calculate density?</h3>

The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;

Density = mass ÷ volume

According to this question, a piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The density can be calculated as follows:

Density = 17.1g ÷ 17.00mL

Density = 1.005g/mL

Therefore, the density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.
