Question

The green pigment, chlorophyll a, absorbs red light, theenergy from which powers photosynthetic processes in plants andalgae.
Chlorophyll a is 6.27% nitrogen by mass.
Each molecule of chlorophyll a contains 4 nitrogen atoms. What is the molecular mass of chlorophyll a?
What mass of magnesium is to be found in 3.59 g of chlorophylla thank you i'll rate lifesavior!!! What is the molecular mass of chlorophyll a?
What mass of magnesium is to be found in 3.59 g of chlorophylla thank you i'll rate lifesavior!!! thank you i'll rate lifesavior!!!

Explanation / Answer

The molecular formula of chlorophyll a is C55H72MgN4O5
The atomic mass of Nitrogen is 14g. We know the 6.27% ofthe entire mass of chlorphyll a is the mass of four N.

4 * 14 g = 0.00627 * Molar mass of chlorophyll a Molar mass of chlorophyll a = 893.14 g
893.14 g of chlorophyll a contains 24.3 g of Mg 3.59 g of chlorophyll a contains x g ofMg x = ( 24.3 * 3.59 ) / 893.14 = 0.0976 g ofMg
