A rock has a mass of 416 grams and when placed in a beaker of water, the level rose to 523 mL. The beaker was originally filled
vagabundo [1.1K]

Answer:

The answer is

<h2>2.55 g/mL</h2>

Explanation:

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

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

From the question

mass = 416 g

volume = final volume of water - initial volume of water

volume = 523 - 360 = 163

volume = 163 mL

The density is

density =  \frac{416}{163}  \\  = 2.552147239...

We have the final answer as

<h3>2.55 g/mL</h3>

Hope this helps you
