Solution
To determine the number of moles of water in 3500 mL, we need to know the concentration of water in the solution.

Assuming the solution is pure water, we can convert the volume in milliliters to liters:

3500 mL = 3.5 L

The molar concentration of water is 55.5 mol/L (at room temperature and pressure). Therefore, the number of moles of water in 3.5 L is:

moles of water = concentration x volume
moles of water = 55.5 mol/L x 3.5 L
moles of water = 194.25 mol

Therefore, there are 194.25 moles of water in 3500 mL (or 3.5 L) of pure water.
