A mole of water at STP occupies approximately 18 cc. Take an eye dropper and add drops of water to a graduated cylinder until it equals 18cc. (We'll assume that your eyedropper technique is consistent enough that each drop is equal...otherwise you need more accurate equipment...you could also do this by weight). From this you can calculate that your drop is .X of a mole (For example if 18cc is 1800 drops then X is 0.01. From there you can calculate how many molecules of water are in your drop by multiplying Avogadro's number by your calculated X...and multiplying by 3 since their are 3 atoms (2H and 1O) per molecule of water to get the number of atoms in your drop.
If accuracy is required you'd best hit the lab for equipment...as the chances of a truly accurate answer anywhere else are slim and none. But you could do this for fun with a 1cc TB syringe. You do the math.

How do you find number of atoms in water mole?
In order to go from moles to number of particles in any substance you simply multiply the number of moles by Avagadro's number (6.02 x 10^23). Once you have the number of molecules (in general it's particles), you would multiply the number of molecules by the number of atoms in each molecule. In water there are 3 atoms per molecule (2 hydrogens, 1 oxygen),so you'd mulitply by 3.Summarizing: You have to multiply the number of water moles by Avagadro's number (6.02 x 10^23) and then again by number of atoms per molecule (3).n timesA times 3 = number of atoms in 'x' moles of water

How many hydrogen atoms are in 738 grams of water?
To find the number of hydrogen atoms, we need to first determine the number of water molecules in 738 grams of water. Then, using the molecular formula of water (H2O), we know that each water molecule contains 2 hydrogen atoms. Finally, we can calculate the total number of hydrogen atoms by multiplying the number of water molecules by 2.
How many atoms are there in 0.575 grams cesium?
To find the number of atoms in 0.575 grams of cesium, you first need to convert grams to moles using the molar mass of cesium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in one mole of cesium. Multiply the number of moles by Avogadro's number to find the number of atoms in 0.575 grams of cesium.
How do you find the number of atoms in 6.21 mol of Mg?
To find the number of atoms in 6.21 mol of Mg, you would use Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, for 6.21 mol of Mg, you would multiply the number of moles by Avogadro's number to get the number of atoms.
How can you find the mass from the number of atoms?
protons plus the number of neutrons.
How can you calculate no of moles from no of atoms?
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
What is the total number of atoms in the formula unit for calcium nitride?
The formula unit for calcium nitride is Ca3N2. To find the total number of atoms, you add the number of atoms in each element together: 3 calcium atoms + 2 nitrogen atoms = 5 atoms in total.
What is the number of hydrogen atoms in 90 amu of ethane?
To find the number of hydrogen atoms in 90 amu of ethane (C2H6), use the molar mass of ethane to determine the number of moles present. Next, use the molecular formula of ethane to calculate the number of hydrogen atoms in one mole, and then multiply by the number of moles present to find the total number of hydrogen atoms.
How many copper atoms are in a pure copper statue with a mass of 148kg?
To find the number of copper atoms in the statue, you need to first determine the number of moles of copper using its molar mass. Then, you can multiply the number of moles by Avogadro's number to find the number of atoms. Given that the molar mass of copper is approximately 63.55 g/mol, you can follow these steps to calculate the number of copper atoms in the statue.
