6 Molecules.


The big number in the front it called the coefficient, and it indicates the number of molecules of a compound there are in a formula. In this case, the coefficient is 6 and so there are 6 molecules of #C_6 H_12 O_6#.

The smaller, lower numbers after each element symbol are called subscripts and they indicate how many of each atom are in a single molecule.For example, there are 12 Hydrogen atoms in one molecule of #C_6 H_12 O_6# and so there are 48 in #6C_6 H_12 O_6#.
