Question

calculate molecular masses of- H2,O2 and CL2

Answer 1

Molecular masses of H2 = 2 * molar masses

                                         = 2 * 1 u

                                          = 2u

Molecular masses of O2 = 2 * molar masses

                                          = 2 * 16u

                                          = 32u

Molecular masses of CL2 = 2 * molar masses

                                            = 2 * 35.5u

                                           = 71u


Hope this helps!

Answer 2

1)H2
H×2
1×2=2u
2) O2
O×2
16×2=32u
3)Cl2
Cl×2
35.5×2=71u....
All answers are right.. pls mark as brainlest answer... i will be thanksful to you... pls rate...
