Question

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?

Answer 1

1.7 g/mL

Step-by-step explanation:

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

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

From the question

volume = final volume of water - initial volume of water

volume = 16.3 - 15 = 1.3 mL

We have

`density = (2.21)/(1.3) = 1.7 \\`

We have the final answer as

1.7 g/mL

Hope this helps you
