Solve this:
Q. Note: 1. Atomic mass of an element is a relative mass of one atom and not the absolute mass.
2. The mass of an object is a measure of the quantity of matter that it contains, whereas the mass of an object is a measure of the gravitational pull that it experiences. Mass and mass are proportional to each other, but they are not identical, e.g., An astronaut would have the same mass (contains the same quantity of matter) but different mass on Earth and on Mars.
