Answer:

Explanation:

58.85 divide 12           6,97  divide 1                37,18 divide 16

4,9                                  6,97                             2.32           /divide 2,32

2.11                                 3.00                              1

                                                  C2H3O=12•2+1•3+16•1

                                                              =24+3+16

                                                              =43

                       Mr=86 divide 43

                           =2•C2H3O=

                           =86
