The chlorophyll-a molecule, C55H72MgN4O5, is important in photosynthesis.
(a) Determine its molecular mass (in atomic mass units)
(b) What is the mass (in grams) of 3.00 moles of chlorophyll-a molecules?
To find the molecular mass of chlorophyll, we need to know the atomic mass of each element in the molecule. They are
C - ...
The moles, molar mass and molecular weight are calculated for atomic mass units. The importance of photosynthesis are given.
