Paraphin [41]

Answer:

We have the final answer as

<h2>9.85 g/mL</h2>

Explanation:

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

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

From the question

mass of substance = 223.5 g

volume = final volume of water - initial volume of water

volume = 68.3 - 45.6 = 22.7

volume = 22.7 mL

It's density is

density =  \frac{223.5}{22.7}  \\  = 9.84581497797...

We have the final answer as

<h3>9.85 g/mL</h3>

Hope this helps you
