Question

chlrophyll 3.68% magnesium by mass. calculate number of magnesium 500 grams of the complex​

Answer 1

Answer:

Mass of chlorophyll = 2.0 g

Percentage of Mg = 2.68 g

Mass of Mg in 2.0 g of chlorophyll = 2.68 x 2.0/100 = 0.054 g

6.022 X 1023 atoms of magnesium = 24 g

24 g of Mg contains = 6.022 X 1023 atom

0.054 g of Mg contains = 6.022 x 12.0/24 = 1.3 X 1021 atoms
