I am having 10-15 nm size gold nanoparticles synthesized by chemical method. In the next step, I need to use a 5 nM concentration. It would be a great help if anyone helps me with how to calculate the molecular weight of the gold nanoparticles.

If you have enough material, you could measure the density of a dispersion of your particles in water using a pycnometer. It's non-destructive.
10mL of a 1% w/w dispersion could easily be measured with a $10 glass pycnometer.

Look up for the molar extinction coefficient for the range size of your nanoparticles
