Chemistry

Answer:

You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up. You can use this relation backwards too -- if you know what material an object is made of, you can look up its density in a book. hOPE THIS HELPS! =)

NeTakaya

Answer:

<h3>The answer is 26.22 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density of iron = 7.874 g/cm³

volume = final volume of water - initial volume of water

volume = 57.65 - 54.32 = 3.33 mL

We have

mass = 7.874 × 3.33 = 26.22042

We have the final answer as

<h3>26.22 g</h3>

Hope this helps you
