Xylose, a sugar isolated from wood, has the empirical formula CH2O. If a 6.25 mole sample
of xylose has a mass of 938.3 g, what is xylose's molecular formula?

Answered by DrBob222
mols = grams/molar mass
Solve for molar mass.

Then empirical mass is
C = 12
H = 2
O = 16
-------
30
molar mass = empirical mass*x
Solve for x and substitute into
(CH2O)<sub>x</sub> or you can write it as C<sub>x</sub>H<sub>2x</sub>O<sub>x</sub>
