<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>
