Answer:

Molecular mass of K2Cr2O7 is 294 amu

Explanation:

Molecular mass of K2 Cr2 O7

          =2×(Atomic mass of K) +2×(Atomic mass of Cr) +7×(Atomic mass of O)

                                                  =2×(39)+2×(52)+7×(16)

                                                  =78+104+112

                                                  =294 amu
