A piece of metal with a mass of 611 g is placed into a graduated cylinder that contains 25.1 mL of water rising the water level
djyliett [7]

Answer:

The answer is

<h2>2.64 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 611 g

volume = final volume of water - initial volume of water

volume = 256.7 - 25.1 = 231.6 mL

The density of the metal is

density =  \frac{611}{231.6}  \\  = 2.638169257...

We have the final answer as

<h3>2.64 g/mL</h3>

Hope this helps you
