How many molecules will be present in a drop of water having a volume of 0.06 cc?

Thus, a drop of water weighing 0.06 gas contains 2.007×1021 molecules of of water in it.

How many molecules of H2O are in a drop of water?

There are 1.67 x 1021 or 1.67 sextillion water molecules in a drop of water. There are three atoms per water molecule.

How many molecules are present in water?

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g .

How many molecules are there in water?

There are therefore 6.02 × 10 23 water molecules in a mole of water molecules. There also would be 6.02 × 10 23 bananas in a mole of bananas, if such a huge number of bananas ever existed.

How many molecules of water should be present in a drop of water with volume 0.05 cc?

1. 67×1022.

How many H2O molecules are in one mole of water?

6.02 × 10 23
The mole is the SI unit for amount of a substance. 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 water molecules are there in 1 drop of water at room temperature?

The number of water molecules present in a drop of water (Volume 0.0018 ml) at room temperature is. 6.023×1019. 1.084×1018.

What is meant by 18 molecules of water?

Therefore 18 mole of water will contain 18×6.023×1023 number of molecules. – The third option is given as 18 molecules of water and hence the number of water molecules is 18. – The number of moles in 1.8 grams of water can be given as follows.

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

=1.667×1021 molecules.

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

How many molecules of water are there in 50 mg of water?

So, 50 mg ( 50 x 10 -3 g) water will contain = 6.022 x 10 23 x 50 x 10 -3 / 18 = 1.67 x 10 21 molecules of water. Was this answer helpful? Was this answer helpful?

What is the mass of a drop of water in grams?

In other words, 1 milliliter of water has a mass of 1 gram. 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)

How many atoms are there in a droplet of water?

Put another way, there are 1.67 sextillion water molecules in a water drop. Now, the number of atoms in a droplet of water is 3x the number of molecules: Or, there are about 5 sextillion atoms in a drop of water.

How many moles of water are in a 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
