The volume of water in a graduated cylinder was increased from 52.0 mL to 75.5 mL when a piece of irregular metal was placed in the water. If the piece of metal has a mass of 265.6 g, what is the density of the metal?

11.30 g/mL

Explanation:

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

volume = final volume of water - initial volume of water

volume = 75.5 - 52 = 23.5

From the question we have

We have the final answer as

11.30 g/mL

Hope this helps you

NO
The first answer is wrong because it’s just 2 oxygen molecules connected together
The second answer is correct, there is a difference in electronegativity
The third answer is wrong because it’s ionic bond not covalent bond
And obviously the forth one is wrong it’s just Na
