Question

find the number of molecules 54g of water?
find the number of moles of 54g
of water ?​

Answer 1

Explanation:

Molar mass of water=18g.

Number of moles in 54g water=54/18=3 moles.

Number of molecules of water=Number of moles×Avogadro number=3×6.022×10^23= 1.8066×10^24 molecules.

Answer 2

Answer:

moles = 3

molecules = 1.8066*10^24

Explanation:

moles = given mass/molar mass=54/18=3

molecules = moles * avagadro number = 3*6.022*10^23

=1.8066*10^24
