Explanation:
The weight of the container after the wax hardens is 0.18 N.
<h3>What is the law of conservation of mass?</h3>
We know that according to the law of the conservation of mass, the mass of an object can neither be created nor destroyed but it can be changed from one form to the other.
Looking at this law, we know that the mass would not change even after the time that the wax must have hardened. The total mass of the wax would have to be a constant.
Total mass would now be;
Mass of the wax + mass of the container
= 3 g + 15 g
= 18 g
Weight = 18/1000 * 9.8 m/s^2
= 0.18 N
