Question

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 with 360 mL of water. What is its density?

Answer 1

The answer is

2.55 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 = 416 g

volume = final volume of water - initial volume of water

volume = 523 - 360 = 163

volume = 163 mL

The density is

`density = (416)/(163) \\ = 2.552147239...`

We have the final answer as

2.55 g/mL

Hope this helps you
