For mass % only the mass is required for this calculation. When only moles are known, than also molar composition - formula and atomic- or molecular masses are needed to calculate % of composition
The chemical formula is not necessary.
Volume-volume promblems
An equation would require a process... such as the equation for a specific step in the synthesis, which I doubt you where asking about. I'm assuming you mean the chemical name: 9,10-Didehydro-N,N-diethyl-6-methylergoline-8ß-carboxamide or the chemical formula: C20H25N3O
That's sodium chromate. However, the correct formula would actually be Na2CrO4, because sodium is a +1 metal, and the chromate polyatomic has a -2 charge. Therefore it will require two sodium atoms.
FalseAll chemical reactions require an initial input of energy called activation energy.
not water but acid, and there are others
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
Soxhlet extraction is the usual method; this doesn't require you to "calculate" anything, except to the extent that "(weight of fat/weight of original sample) * 100" is a calculation.
We know that Al2O3 is the chemical formula for aluminum oxide.
Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.

all foods require either physical or chemical digestion.
endothermic reactions require energy
