It is not typical to refer to the weight of literally a single molecule (one nitrogen and four hydrogens) but to a "mol" or 6.022 x 10^23 molecules.
But, if that is actually what you mean, the mass of a single molecule of NH4 can be determined like this.
[(molar mass N x 1) + (molar mass H x 4)] / (6.022 x 10^23)
that will give you the answer in grams.
[(14.01)+(1.01 x 4)]/(6.022 x 10^23) = (18.05)/(6.022 x 10^23) grams
i don't have a calculator, plug it in and you've got it!
