Introduction:
In order to determine the number of atoms in a given mass of calcium, we need to know the molar mass of calcium and use the concept of Avogadro's number.
Step 1: Determine the molar mass of calcium:
The molar mass of calcium (Ca) is approximately 40.08 grams per mole. This means that one mole of calcium contains 40.08 grams.
Step 2: Calculate the number of moles of calcium:
To calculate the number of moles of calcium in 0.8 grams, we divide the given mass by the molar mass of calcium:
Number of moles = Mass of calcium / Molar mass of calcium
Number of moles = 0.8 grams / 40.08 grams per mole
Number of moles ≈ 0.01996 moles
Step 3: Determine the number of atoms:
Avogadro's number (6.022 x 10^23) represents the number of atoms or molecules in one mole of a substance.
To calculate the number of atoms in 0.01996 moles of calcium, we multiply the number of moles by Avogadro's number:
Number of atoms = Number of moles × Avogadro's number
Number of atoms = 0.01996 moles × 6.022 x 10^23 atoms/mole
Number of atoms ≈ 1.199 x 10^22 atoms
Conclusion:
Therefore, 0.8 grams of calcium contains approximately 1.199 x 10^22 atoms.
