Answer:
17.9 Moles
Explanation:
In the one-kilogram iron weight there are 1.08·1025 atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms
To find the number of moles, determine the molar mass of iron. Then divide the given mass by its molar mass, or multiply the given mass by the reciprocal of the molar mass, which is more common.
Answer:
1.Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
2.The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.
3.For every action there is an equal and opposite reaction.
