instructions:

1. show all work and include units.
2. use the formulas:

• volume of a rectangular solid: v= length x width x height
• volume of an irregular object: v= final water level - initial water level
• density: d= mass/volume
• floating/sinking: compare object density to water (1 g/ml).

part a: liquid volume – read the meniscus

1. a graduated cylinder contains water. the bottom of the meniscus reads 56 ml.

volume = ______ ml

1. a test tube has liquid that measures 24.5 ml at the meniscus.

volume = ______ ml

1. a beaker shows water at 102.2 ml.

volume = ______ ml

1. a cylinder has liquid at 39.8 ml.

volume = ______ ml

1. water in a flask reads 75.3 ml.

volume = ______ ml

Explanation:

Problem 1

Step1: Determine volume from meniscus

The volume is the reading of the bottom of the meniscus, which is 56 mL.

Step1: Determine volume from meniscus

The volume is the reading at the meniscus, which is 24.5 mL.

Step1: Determine volume from beaker

The volume is the reading shown, which is 102.2 mL.

Answer:

56
