<h2>~AnonymousHelper1807</h2> The amount of Ca is not limiting, we have : 2.87g of O will produce : 2.87 / 56.1 = 0,051158645 mol of CaO
What is Mass?
Mass is a property that represents the amount of matter in a sample. Mass is often expressed in grams (g) and kilograms (kg) (kg). Mass can alternatively be defined as the property of matter that provides it the ability to resist acceleration. The more mass an object has, the more difficult it is to accelerate.
