Question

calculate number of moles and molecules of urea present in 5.6 gram of urea​

Answer 1

Answer:

Molar mass of urea = 60g

No of moles = given mass/molar mass

                  = 5.6/60

                   =0.09 moles

No of molecules = Avogadro no * moles

                            = 6.022 * 10^23 * 0.09

                           = 0.56 *10^23 molecules are present
