For clarification:
Molar mass, meaning mass per one mole of the molecule.
eg: one mole of water = H2O, two moles of water = 2H2O
It really depends where the tap water is from. Besides that tap water is a mixture, not a compound. (The ions are not all bonded) So it doesn't have a chemical equation..
If I were you I'd just use the Molar Mass of pure water in your calculations, or ask the teacher.
(H = 1.008, * 2 = 2.016
O = 16.00
Molar Mass of H2O =2.016 + 16.00 = 18.016 g/Mole)
Assuming that by one drop, you mean one millilitre, the process becomes quite simple:
This is an approximate answer, and the more decimal places of the measurement you start with, the more accurate the answer will be. My answer is accurate to 3d.p. (unless I am mistaken), but there are more decimal places in the actual measurement of the mole.
If you're wondering what I just did, it's time for a little chemistry. The first step can be worked out from the simple conversion of 1m3 of water to 1 tonne. By simplifying this, we get 1dm3 of water is 1kg, and finally 1cm3 of water is 1g. The second step is a little more complicated. The Mr is the formula mass, which is the relative mass of each of the components of water (2H+1O), which is essentially the bigger of the two numbers next to each element in the Periodic Table. The number of moles is equal to the given mass (1g) divided by the Mr, which gives 1/18. The number of molecules in one mole can be taken from a number of sources, but most take it to be 6.023 * 1023 molecules.
As pertaining to what solute? Due to water's molar mass of 18 g/mole and that one liter of water contains 1000 g of water, there are 1000/18 which equals 55.5555 moles/liter of water in water.
Any other dissolved substances would depend on where you got the tap water. Some places have 'hard water' that contains calcium ions or iron ions or others and they would have some concentration of those substances. Other places have 'soft water' which doesn't contain those minerals, but could contain some sodium or potassium or other minerals. All of these minerals would have some concentration that would be different in various locations. Most of the substances are in such small amounts that, when analyzed, they are not even reported as molar concentrations, but as ppm, parts per million.
I'm not sure what you mean by the word particle. In each water molecule there are three atoms: two of hydrogen and one of oxygen.

The molar mass is the sum of atomic weight of the atoms contained in a molecule. Example: water, H2O The molar mass is: 2 x 1,008 + 15,999 = 18,015 Molar mass is used in many calculus in chemistry.

The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
Molar mass of H2O = 18.01528 g/mol

The molar mass of sodium acetate is 82,03. The molar mass of carbon dioxide is 44,01.
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
