What is the density (g / mL) of a substance that has a mass of 8.11 g and, when placed into a graduated cylinder, causes the wat
MAXImum [283]

Answer:

<h3>The answer is 0.42 g/mL</h3>

Explanation:

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

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

From the question

mass = 8.11 g

volume = final volume of water - initial volume of water

volume = 44.72 - 25.26 = 19.46 mL

We have

density =  \frac{8.11}{19.46}  \\  = 0.416752312...

We have the final answer as

<h3>0.42 g/mL</h3>

Hope this helps you
