The chlorophyll a molecule contains 2.72% magnesium by weight. What is the minimum molecular weight of chlorophyll a if the atomic weight of magnesium is A (Mg) = 24.3?
Determine what is the minimum mass of chlorophyll a, if the molecular mass of magnesium is 24.3:
24.3 corresponds to 2.72% of the total mass of the molecule,
x – the mass of chlorophyll is 100%.
24.3 – 2.72%
x – 100%,
x = 893
