Correct statement in the following is/areA) Mass of one gram molecule oxygen is 32 gramsB) Mass of one gram atom oxygen is16 gramsC) Mass of one molecule oxygen is 32 amuD) Mass of one oxygen atom is 16 amu

A) MW of Oxygen = 32; Gram mole(Gram molecule) = 32gB) AW of Oxygen = 16; Gram atom = 16gC) GMW of Oxygen = 32g; 32g of Oxygen contain No molecule    Wt of one molecule of oxygen  =                                                  = 32 amu (or) 32uD) GAW of Oxygen = 16g16 g of oxygen contain N0 atomWt of one atom of Oxygen =                                        = 16 amu (or) 164A,B,C,D are correct.
