Explanation:
Detailed explanation-1: -2.0 moles of H2O corresponds to 2.0 x 6.02 x 10^23 molecules. This means that there are approximately 1.2 x 10^24 molecules of H2O in 2.0 moles.
Detailed explanation-2: -Substituting the value of N is the above expression. Thus, 0.0332mole 0.0332 m o l e of water H2O H 2 O contain 2.0×1022 2.0 × 10 22 molecules.
Detailed explanation-3: -2 x [6.022 x 10^23] =1.2044 x 10^24 molecules in 2 moles.
Detailed explanation-4: -To obtain the mass of 2 moles of water, we simply the number of moles by molar mass: 2 moles X [2(1) + 16]g/mole = 36 g.
