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 water
Our (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.

To determine the number of water molecules swallowed from a cup of water, you would first need to know the volume of water consumed. Then, you can use Avogadro's number (6.022 x 10^23) to calculate the number of molecules, as one mole of water contains Avogadro's number of molecules.

How does the number of atoms in the molecules that are found in air and water compare with the number of atoms in molecules that are found in food?
Molecules in air and water tend to be simpler and have fewer atoms compared to those found in food. Food molecules are typically more complex and larger in size, containing more atoms due to their role in providing energy and nutrients to living organisms.
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
36g of water have how many molecules?
To find the number of water molecules in 36g of water, you first need to convert grams to moles using the molar mass of water (18g/mol). Then you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of water. Finally, you multiply the number of moles by Avogadro's number to get the total number of water molecules in 36g.
How many molecules are in 10 grams?
The number of molecules in 10 grams of a substance depends on the molecular weight of the substance. You can calculate the number of molecules by first converting the mass to moles using the molecular weight and then using Avogadro's number (6.022 x 10^23) to determine the number of molecules.
If 5.0 mols of C3H8 react how many molecules of water are formed and gt?
The number of water molecules obtained is 120,44281714.10e23.

How many molecules of water does a 50g sample of H2O have?
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
How many molecules of water are produced if 2.0g of sodium sulfate are produced in the above reactionH2SO4+2NaOH=H2O+Na2SO4?
The reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.
If a snowflake contains 1.8 1018 molecules of water how many moles of water does it contain?
To determine the number of moles of water in the snowflake, divide the number of molecules of water by Avogadro's number, which is approximately 6.022 x 10^23. So, 1.8 x 10^18 molecules of water divided by Avogadro's number is approximately 3 x 10^-6 moles of water in the snowflake.
Is there more water molecules in thermal energy when its hot or cold?
The number of water molecules is not dependent on temperature.
What is something that can swallow you and you can swallow it?
Water. It can swallow you in a flood or drowning incident, and you can swallow it to stay hydrated or to consume beverages.
How many molecules are in 6.9 g H2O?
To determine the number of molecules in 6.9 g of water (H2O), you first need to convert grams to moles. The molar mass of water is approximately 18 g/mol. Therefore, 6.9 g is equal to 6.9/18 = 0.383 moles of water. Next, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in 0.383 moles of water, which is approximately 2.3 x 10^23 molecules.
36g of water have how many molecules?
To find the number of water molecules in 36g of water, you first need to convert grams to moles using the molar mass of water (18g/mol). Then you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of water. Finally, you multiply the number of moles by Avogadro's number to get the total number of water molecules in 36g.
How many molecules of water are in 5.65 moles of water?
There are approximately 3.40 x 10^24 molecules of water in 5.65 moles of water. This can be calculated using Avogadro's number (6.022 x 10^23 molecules/mol) multiplied by the number of moles.
How many molecules are there in 39 grams of water?
Steam is just water. Water weighs the same per molecule regardless whether it is ice, water, or steam. That said, the molecular weight of water is right at 18 g/mole. So it seems that 9.0 grams of steam is about half a mole of water. Therefore we just divide avagrado's number by 2 and we get: 6.022 x 1023 / 2 = 3.011 x 1023 molecules
How many H2O molecules are in a mole of water molecules?
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
