To figure out the mass, you will need to use a scale or balance. Here's a step-by-step guide on how to find the mass:
1. Choose a scale or balance: Ensure that you have access to a reliable scale suitable for measuring the mass of objects. A digital scale is commonly used and can be found in most households.
2. Place the object on the scale: Put the object whose mass you want to find onto the scale. Make sure the object is stable and properly positioned to ensure an accurate reading.
3. Read the measurement: Look at the display on the scale to know the mass of the object. Usually, the mass is displayed in grams (g) or kilograms (kg). If the scale shows a measurement in a different unit, you might have to convert it to grams or kilograms.
4. Record the measurement: Write down the mass of the object in a suitable unit of measurement. If necessary, round the value to the appropriate number of decimal places based on the accuracy of the scale.
It's important to note that if you need to find the mass of an irregularly shaped object or a collection of objects, you can use the concept of displacement. You can fill a container with water and measure its mass, then place the object in the water and measure the new mass. The difference in mass between the two measurements will be the mass of the object.
