Question

a graduated cylinder has 8.0 ml of water initially. a piece of graphite is placed in the cylinder, displacing the level to 14.6 ml. what is the volume of the graphite piece in cubic centimeters? ? cm³ record your answer to the tenths place.

Explanation:

Step1: Recall volume displacement principle

The volume of the object (graphite) is equal to the volume of water displaced, which is the final volume minus the initial volume. Also, \(1\space mL = 1\space cm^3\).

Step2: Calculate the volume of displaced water

Final volume of water is \(14.6\space mL\), initial volume is \(8.0\space mL\). So the volume of graphite \(V=14.6 - 8.0\)
\(V = 6.6\space mL\)

Step3: Convert mL to \(cm^3\)

Since \(1\space mL = 1\space cm^3\), \(6.6\space mL=6.6\space cm^3\)

Answer:

\(6.6\)
