What is the most correct measurement for the volume off the liquid shown in the image?

• 30.25mL

• 32.0mL

• 35mL

• 35.0mL

• 32.5mL

Answer explanation

In this example, the graduations (ticks) go up by 2. When the graduations increase by 2 there is no decimal place in the measurement. The unit when measuring with a graduated cylinder is mL.
