42.4 ml is the volume in milliliters of the lead ball if a lead ball is added to a graduated cylinder containing 50.6 ml of water.
<h3>What is a graduated cylinder?</h3>
A tall narrow container with a volume scale is used especially for measuring liquids.
The graduated cylinder contains water
mL is a volume unit.
Water volume = 50.6 ml
The lead ball caused an increase in volume from 50.6 ml to 93.0 mL.
The new volume is the lead ball volume plus the original water volume :
Final volume = Vlead ball+ Water original volume
![93.0 mL= V_(lead ball) +50.6 ml](https://tex.z-dn.net/?f=93.0%20mL%3D%20V_%28lead%20ball%29%20%2B50.6%20ml)
![V_(lead ball) = 93.0 mL - 50.6 ml](https://tex.z-dn.net/?f=V_%28lead%20ball%29%20%3D%2093.0%20mL%20-%2050.6%20ml)
![V_(lead ball) = 42.4 ml](https://tex.z-dn.net/?f=V_%28lead%20ball%29%20%3D%2042.4%20ml)
Hence, 42.4 ml is the volume in milliliters of the lead ball.
