In short, a LOT!
Here's the calculation. First convert a teaspoon of water in milliliters:
(see the linked question for the answer!): 1 US teaspoon = 4.92892161 milliliters
At 4°C, the density of water is exactly 1.00 gram per milliliter, so 1 teaspoon of water weighs 4.92892161 grams.
The molecular weight of water is:
2*(1.00794) + 15.9994 = 18.01528 grams per mole
So in 1 teaspoon, there are this many moles:
4.92892161 grams ÷ 18.01528 grams per mole = 0.273596725 moles
There are 6.0221415 × 1023 molecules in a mole of water, so in 1 teaspoon of water, there are this many molecules:
0.273596725 moles * 6.0221415 × 1023 molecules/moles = 1.64763819 x 1023 molecules
Water having the capacity of suspending solubles is unquestionable (i.e. sulfur, iodine, iron even mercury) but for a one molar solution one needs know either what is in the water already (H2O+ unless it is distilled water you are discussing at least) then it would be incumbent on what the waters actual soluble substances atomic,molecular, or compound weights were relative the solutes amount in relation to Avogadro constant - it appears that all are quantitatively attributing it a measuring question of H2O without regard to it's contents in suspension or their molar weights molarity impure or to be used for a molar solution.
A mole of water molecules would just about fill a teaspoon.
When salt is dissolved in water, the mass of the water increases without a significant increase in volume, increasing the density of the solution. This is because the added salt molecules displace some of the water molecules and fill the space in between them, making the solution denser.
When ethanol and water are mixed, they form a solution with a volume less than the sum of the individual volumes due to the molecules of ethanol and water packing closely together in the solution. This phenomenon is known as partial miscibility, where the molecules of ethanol and water interact with each other in a way that reduces the total volume of the solution.
Which is NOT true? 1. Molecules in a gas are close together compared to their large molecular size. 2. A solid has a set shape and volume. 3. Molecules in a gas spread out to fill their container. 4. Molecules in a liquid have more freedom of movement than those in a solid. 5. Molecules in a solid are close together.
The gaseous phase has molecules that will diffuse to fill their container. Gas particles are in constant, random motion and will spread out to occupy the available space uniformly.
A mole of water molecules would just about fill a teaspoon.

You would need to fill the teaspoon three times to equal one tablespoon.
It depends on the size of the cup.
No, it takes the same number of water molecules to fill up a certain space whether they are in the form of ice or liquid water. In ice, the water molecules are just held in a more structured arrangement compared to the more freely moving molecules in liquid water.
The red food dye would fill in the spaces in the molecules thus turning it red. When there are no spaces the the dye would collect in the bottom of the container
That would be 16.6 tablespoons
It depends on the size of the cup.

The only way to answer this is to know what substance you are measuring. Tablespoon is a measurement of volume (15 ml) and gram is a measurement of weight. 120 grams of water would fill a volume of 120 ml or 8 tablespoons whereas 120 grams of salt (which is about 2.1 times denser than water) would only fill about 3.8 tablespoons.
Fill a sink with warm water and a tablespoon of Cascade Dawn, scrub all dishes in it, then rinse off with clean cold water, preferably in adjoining sink
Water molecules are smaller than alcohol ones. Water ones can fit between alcohol ones. Fill a container with pure alcohol to the top and add water. A certain amount will go into the container and not cause it to overflow.
