Question

numerical on molecular mass and mole concept​

Answer 1

Answer:

Solution. Molar Mass of H2O H 2 O = 2 + 16 = 18 g/moles. So ,number of moles of H2O H 2 O = Mass/Molar Mass = 54/18 =3 moles. Now 1 moles = 6.022×1023 6.022 × 10 23 molecule. So 3 moles will have 18.066×1023 18.066 × 10 23 molecule.
