A lot! Here is the calculation:
The molar mass of water is 18 grams per mole. So in 18 grams of water, there are 6.02 x 1023 molecules.
One gallon of water is equal to 3.7854118 liters. If we assume that the water is at 4 °C (to keep things simple), the density of water is exactly 1 gram per milliliter, or 1 kilogram per liter. So 1 gallon of water at 4 °C weighs exactly 3.7854118 kilograms, or 3785.41118 grams.
If one mole of water weighs 18 grams, then there are 210.30 moles of water in a gallon. Since one mole of water is made up of 6.02 x 1023 molecules, in one gallon of water there are 1.266 x 1026 molecules.
That is: 126600000000000000000000000 molecules!
If we multiply that by the number of atoms in a single water molecule -- 3 atoms -- then we get:
379800000000000000000000000 atoms!

If you want to know how many atoms are in a gallon of water, just multiply that by three, since there are 3 atoms in H2O. So there are are 3.798 x 1026 atoms in a gallon of water
That is: 379800000000000000000000000 atoms!

∙ 13y ago1 gallon water * (3.79 liters/1 gallon) * (1000 grams/1 liter) = 3790 grams water
3790 grams water / (18.015 grams/mole) = 210. moles water
210. moles water * 6.02*1023 molecules/mole = 1270*1023 water molecules
each water molecule contains 2 hydrogen atoms and 1 oxygen atom, so:
2530*1023 atoms H + 1270*1023 atoms O = 3800*1023 total atoms = 3.80*1026 total atoms
One gallon of water weighs approximately 8.34 pounds, which is equivalent to about 0.457 moles of water.

1 gallon = 3.785 L H2O = 3785 g H2O
3785 g H20 * (1 mol / 18.02 g) (6.02x10^23 molecules/mol) = 1.265x10^26 molecules

When one mole of sodium nitrate (NaNO3) is added to water, it dissociates into one mole of sodium ions (Na+) and one mole of nitrate ions (NO3-). So, one mole of sodium nitrate produces two moles of solute particles in total when dissolved in water.
Roughly zero. One litre is more water than I can drink in one go, and 0.82 moles of water is too small to see.
