The number of molecules in the jar probably is a few more decimal placements than Avogadro's number.

Yah sure you betcha.

Avogadro's number = number of units in a mole.

1 mole of water ~ about 18 grams of water.

1 liter of water ~ 1000 cc of water ~ 1000 g of water (temperature and density...)

there are more or less 55 moles of water in a liter.

I was figuring about 10**25th.

For each molecule, you need 4 numbers to describe position and linear momentum, another 4 numbers to describe angular momentum, so just given those two attributes we have 10**25**8.

Because a water molecule is V shaped, it can ring or vibrate like a tuning fork, adding another scalar to the equation.

Lotsa zeros. You got the idea.

If a new state of the molecules happens each Planck unit and never repeats, it would take like 10**180 seconds to show all the patterns, this is trillions of trillions of googles times the age of the universe.
