A graduated cylinder is filled with 54.32 cm3 of water. An irregular solid made of iron is carefully placed into the graduated cylinder. The new volume recorded on the graduated cylinder is 57.65 cm3. The density of iron is known to be 7.874 g/cm³. What is the mass in grams of the irregular solid made of iron?

Answer:

The answer is 26.22 g

Explanation:

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

mass = Density × volume

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

26.22 g
