5.29 kg is the mass of 4.87 x 10²⁵ atoms of Zn.
As a measure of inertia, which is a fundamental characteristic of all matter, mass is used in physics. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force.The symbol for mass is m or M. The force exerted on a mass as a result of the acceleration brought on by gravity is measured as weight. W typically stands for weight.
As, we know
Mass of 1 mole of Zn = 65.38 gm/mole
= (65.38/1000) kg/mole
= 0.06538 kg/mole
We know,1 mole = 6.023 × 10²³ atoms.
Thus, moles of Zn = 4.87 × 10²⁵ / 6.023 × 10²³
= 80.87 moles
Therefore, mass of Zn = 80.87 moles × 0.06538 kg/mole
= 5.287 kg ≈ 5.29 kg
