How many water molecules does it take to fill a cup of water?

It depends on the size of the cup.


How many molecules of H2O make up one cup of water?

For a 100 mL cup: approx. 35,45.1023 molecules.


Why when you put ice in a cup and then you put water in it to melt the ice the water level doesnt change?

This is because you are not changing the mass of the water, there are still the same amount of molecules in the cup, although more energized they still occupy [relatively] the same amount of room. I say relatively, because the molecules are slightly more spaces, due to the energy obtained with heat.


How do you determine the number of molecules of water you swallow from a cup of water?

A cup is 8 fluid ounces. And 8 ounces is about 236.6 grams of water.There are 18 grams of water in one mole of water, and a mole of anything contains Avogadro's number of molecules of that compound. That's 6.02 x 1023 molecules.Our (236.6 grams of water) divided by (18 grams per mole) = 13.14 moles of waterOur (13.14 moles of water)(6.02 x 1023 molecules per mole) = 7.91 x 1024 molecules in the 8 ounce glass of water.We had 8 ounces of water. We converted to grams. Then we looked up water to see how many grams of water there were in a mole of water. Then we found out how many moles we had in our cup of water. Then, because we knew how many molecules of water were in a mole (we know because a mole of anything is Avogadro's number of particles of that substance), we multiply to find out how many molecules of water were in the cup of water.That's how we found that there are 7.91 x 1024 molecules in a cup of water.


Why does water at room temperature in a cup evaporating?

Water is evaporated at any temperature because the movement of water molecules is continuous and some molecules at the surface can escape as a gas.

How are the water molecules positioned in the hot cup?

In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.

How long does it take for a sugar cube to dissolve in one half cup of hot water or and in one half cup of cold water?

The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.

How does the float-cup fill valve work in a toilet's water tank?

The float-cup fill valve in a toilet's water tank works by using a floating cup that rises with the water level. When the water level drops, the cup falls and triggers the valve to open and refill the tank. This mechanism helps maintain a consistent water level in the tank.


Which molecules will move faster water molecules in a cup of hot soup or water molecules in a glass of iced lemonade?

Water molecules in a cup of hot soup will move faster than water molecules in a glass of iced lemonade. The higher temperature of the hot soup provides more energy to the water molecules, causing them to move faster.
