Question

a sample of 25.0g of an unknown metal is added to 25.0ml of water in a graduated cylinder and the final volume is 28.5ml what is the density of the metal

Answer 1

The answer is 7.14 g/mL

Step-by-step explanation:

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

`density = (mass)/(volume) \\`

From the question

mass of metal = 25 g

volume = final volume of water - initial volume of water

volume = 28.5 - 25 = 3.5 mL

It's density is

`density = (25)/(3.5) \\ = 7.142857...`

We have the final answer as

7.14 g/mL

Hope this helps you
