Number of atoms=Number of moles×Avogadro's number Number of atoms=0.3moles×6.02×1023atoms/mole 4. Perform the Calculation: - Now, calculate: Number of atoms=0.3×6.02×1023=1.806×1023atoms 5. Round the Result: - We can round 1.806×1023 to 1.8×1023 for simplicity. 6. Conclusion: ...
To calculate the number of atoms and molecules present in a water droplet, you need to know the chemical formula of water. There is one atom of oxygen, and two atoms of hydrogen in each water molecule, each molecule of water contains three atoms, making the formula H2O. Molar Mass of Wa...
32.80 g of Cu × 1 mol Cu / 63.55 g Cu= 0.52 mol of Cu Step 3: Convert Moles to Atoms Using Avogadro’s Number Once the amount of moles is known, the number of atoms in the formula may be calculated using Avogadro's number. Again, use the ratio format. ...
