# How many molecules is in a drop of water?

## How many molecules is in a drop of water?

1.5 sextillion molecules
The accepted average volume of a drop of water is exactly 0.05 mL (20 drops per milliliter). It turns out there are over 1.5 sextillion molecules in a drop of water and more than 5 sextillion atoms per droplet.

How many molecules are there in 250g of water?

Explanation: Glass contains 250g of water. 8.36×1024 molecules of water has 23 of 8.36×1024 atoms of Hydrogen.

### How many number of molecules are in water?

Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

How many molecules are there in h2o?

4 hydrogen atoms and 2 oxygen atoms are found in two water molecules.

#### How many molecules of water are there in 18g of water?

It can be obtained by dividing the given mass (18 g) by molecular mass of water (18 g). – Thus 18 g of water will contain one mole of water, that is 6.023×1023 molecules.

How many molecules are there in 1 drop of water if 1 mL of water contains 20 drops?

6.023×1023 molecules.

## How many molecules of water are there in 36g water?

The total number of molecules in 36 gram of water is 12.044 x 1023.

How many moles are in one drop of water?

One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles

### How many grams are in a drop of water?

A drop of water is 0.05 mL of water, so its mass would be 0.05 grams. One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles

How to calculate the number of atoms in a drop of water?

To calculate the number of molecules and atoms in a water drop, you need to know the chemical formula of water. There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H 2O. So, each molecule of water contains 3 atoms.

#### How many drops of water are there in the ocean?

number of drops of water in the ocean = 2.676 x 10 26 drops. So, there are more drops of water in the ocean than there are atoms in a drop of water. How many more drops depends mainly on the size of your drops, but there are between 1,000 and 100,000 more drops of water in the ocean than atoms in a drop of water.
