Answer:
3.035 × 10²¹ Cu atoms are present in 0.3175 gm of Cu.
Explanation:
Avogadro's law:
According to this law, At STP, equal volumes (for fluids)/moles of all matter contain the same number of molecules/atoms ().
where = Avogadro's number
Calculation:
According to Avogadro's concept,
1 mole or 63 gm of Cu contains 6.023 × 10²³ Cu atoms.
∴ 1 gm of Cu contains atoms.
∴ 0.3175 gm of Cu contains Cu atoms = 3.035 × 10²¹ Cu atoms.
