Answer:
You need to do some simple math here.
look up the mass of each kind of atom. In your molecule that is C, H and O. If you have a periodic table, you can find those masses. the numbers in the cell for each atom is in units of g/mol or amu, depending on whether you are referring to a molar mass or just an individual atom mass.
add up the mass times number of each atom. In your molecule add the mass of 4 hydrogens to 2 carbons to 2 oxygens.
the sum of the atomic masses will be the molecular mass.
