I dont really know how to do this so can you please help me with some of these questions;
How do you measure the moles of a compound?
How do you measure molecular mass and formula mass?
What is the law of chemical combination?

With a molometer.
LOL. You compute moles based on the molar mass of a substance and its mass.
1 mol = molar mass
xxx g A x (1 mol A / molar mass of A) = moles of A
We also know…
1 mole = 6.022 x 10^23 particles (atoms, molecules, etc)
1 mole = 22.4 L of any gas at STP.
Molar mass and formula mass are simply calculated. Add the molar masses of the elements in the compound to get the molar mass of the compound.
