Explanation:
Mass of Urea =
Mass of Urea = 60
Mass of Urea = 60------
Mass of Urea = 60------5.6
Mass of Urea = 60------5.6
Mass of Urea = 60------5.6
Mass of Urea = 60------5.6 =0.0933 moles
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na =0.0933×6.023×10²³
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na =0.0933×6.023×10²³
Mass of Urea = 60------5.6 =0.0933 moles Molecules = mole ×Na =0.0933×6.023×10²³ =0.5621×10²³
