The better estimate for the mass of a guitar would be 4 kilograms.
The mass of a guitar is generally measured in kilograms rather than grams. A more accurate estimate would be 4 kilograms rather than 4 grams.
Guitars are made up of various materials such as wood, metal, and plastic, which can make them relatively heavy. Grams are a unit of measurement used for very small objects or quantities, while kilograms are used for larger and heavier objects.
To give you a better understanding, let's consider some examples. A small bag of sugar typically weighs around 1 kilogram, while a liter of water weighs approximately 1 kilogram as well. These everyday objects are much heavier than 4 grams.
Therefore, the better estimate for the mass of a guitar would be 4 kilograms.
