Question

Calculate the number of magnesium atoms in 2 gram of chlorophyll

Answer 1

Explanation:

Mass of Mg present in 2g of Chlorophyll = (2.68/100) x 2 g = 0.054 g

Also that, 24 g of Mg contain 6.023 x 1023 atoms of Mg

-------------- 1g of Mg = (6.023 x 1023)/24 atoms of Mg

Hence, 0.054 g of Mg will contain (6.023 x 1023/24 ) x 0.054 atoms of Mg = 1.34 x 1023 atoms of Mg present in 2.00 gram of chlorophyll.
