Explanation:

To start an experiment by weighing your dry bar of soap, you would typically use a balance or scale that is present in your science laboratory. First, ensure your scale is calibrated correctly. Once you are sure the scale is ready, place your dry bar of soap on the platform of the scale. The digital or manual screen will give you a reading. The measurement will be in grams (g), possibly with a decimal, depending on the specificity of your scale. This is the mass of your dry bar of soap. Record this number down carefully as you will need it for future calculations or observations.
