In a substance or object, what does mass measure the amount of? a space b matter c gravity d volume

Mass measures the amount of matter in a substance or object. This means it's a way of quantifying how much "stuff" is present without being influenced by the object's location or the effects of gravity. So whether you're on a mountain or floating in space, the mass of an object remains the same! In real-world applications, mass is pivotal in various fields. For example, in cooking, knowing the mass of ingredients ensures that recipes turn out just right. In science, it plays a critical role in calculations for everything from chemistry experiments to understanding motions in physics. So, whether in the kitchen or the lab, mass is your trusty companion!
