Question

You placed an object into a graduated cylinder. The level of water went from
500 ml to 645ml. The object has a mass of 210 g. What is the density of
your object?

Answer 1

Answer:

The answer is 1.45 g/mL

Explanation:

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

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

From the question

mass = 210 g

volume = final volume of water - initial volume of water

volume = 645 - 500 = 145 mL

We have

$density = \frac{210}{145} = \frac{42}{29} \\ = 1.448275862...$

We have the final answer as

1.45 g/mL

Hope this helps you
