7. Marcie fills a graduated cylinder with 15.0mL of water. Paul finds the mass of a marble to be
2.21g, then drops the marble into the graduated cylinder. If the meniscus on the cylinder is
now at 16.3mL, what is the density of the marble?

Respuesta :

Answer:

1.7 g/mL

Explanation:

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

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

volume = final volume of water - initial volume of water

volume = 16.3 - 15 = 1.3 mL

We have

[tex]density = \frac{2.21}{1.3} = 1.7 \\ [/tex]

We have the final answer as

1.7 g/mL

Hope this helps you
