Calculation of Magnesium Atoms in Chlorophyll
Given:
- Mass of chlorophyll = 5.00g
- Magnesium percentage in chlorophyll = 3.68%
Step 1: Calculate the mass of magnesium in 5.00g of chlorophyll
- Mass of magnesium = (3.68/100) x 5.00g
- Mass of magnesium = 0.184g
Step 2: Calculate the number of moles of magnesium
- Molar mass of magnesium = 24.31 g/mol
- Number of moles of magnesium = Mass of magnesium / Molar mass of magnesium
- Number of moles of magnesium = 0.184g / 24.31 g/mol
- Number of moles of magnesium = 0.00757 mol
Step 3: Calculate the number of magnesium atoms
- Avogadro's number = 6.022 x 10^23 atoms/mol
- Number of magnesium atoms = Number of moles of magnesium x Avogadro's number
- Number of magnesium atoms = 0.00757 mol x 6.022 x 10^23 atoms/mol
- Number of magnesium atoms = 4.56 x 10^21 atoms
Therefore, there are approximately 4.56 x 10^21 magnesium atoms in 5.00g of chlorophyll.
