The number of water molecules is maximum in :-

(A)

18 gram of water

(B)

18 moles of water

(C)

18 molecules of water

(D)

1.8 gram of water

NEET - Medical UG-2015 Easy

Answer & Solution:

option :2 

1 mole of water have molecules = \(6.023 * 10^{23}\)

18 grams of water = 1 mole of water 

18 moles of water 

18 molecules of water 

1.8 grams of water = 0.1 mole of water 

So 18 moles of water contains maximum number of water molecules =\(108.414 * 10^{23}\)
