## What is the mass of a drop of water containing 3.55 x 10^22 H2O molecules?

Using the formula,

Number of moles= Number of particles / Avogardo’s value( 6 x10^23)

therefore,

Number of moles of a drop of water is= 3.55 x 10^22 divided by( / ) 6x 10^23

= 0.0591667moles(6sig fig)

Using the formula,

Number of moles= Mass of a substance/ Molecular mass

0.0591667moles= Mass of water divided by Molecular mass of water( 2+16 )

By manipulating of equation,

Mass of water= 0.0591667moles x18

=1.065grams of water

There’s your answer! Hope it helps! 😀

(P.S. please forgive me if my answer is wrong.)

One molecule of water (H2O) contains two atoms of hydrogen – The mass of 1 water molecule in Kg is: mass of H2O (kg) = 18 u * (1.7 x 10⁻²⁷ Kg/1.0 u) = 3.1 x 10⁻²⁶ kg Now, we have the mass of a single water molecule and the mass of the world's oceans: 3.1 x 10⁻²⁶ kg ⇒ 1 water molecule 1.4 x 10²¹ kg ⇒ x = 1.4 x 10²¹ kg * 1 molecule / 3.1 x 10⁻²⁶ kg = 4.5 x 10⁴⁶molecules of waterQuestion: What Is The Mass Of A Sample Of Water Containing 3.55 X 10^22 Molecules Of H2O?

Water | H2O – PubChem – Hydrates generally contain water in stoichiometric amounts; hydrates' formulae are represented using the formula of the anhydrous (non-water) component of the complex followed by a dot then the water (\(\ce{H2O}\)) preceded by a number corresponding to the ratio of \(\ce{H2O}\) moles per mole of the anhydrous component present.Use Avogadro's number (6.022 X 10^23 molecules per mole) to convert H2O molecules to moles of H2O. Then use the molar mass of water (18.02 g/mol) to convert the number of moles to the mass of the water drop.3. Calculate the mass of water lost on heating.
