Expert Answer:

oxidation state of oxygen is -2

lets take metal O.S as +1 or +2 in two cases with its atomic wt. as X

case 1:

for +1 state, its:        M2O+ 2HCl  ----> 2MCl + H2O

                                    2x+16                  x+35.5

 so, it shld be 3/(2x+16)  = 2*5/(x+35.5)   where x is negative, so its not possible to metal be in +1 state

case 2:

for +1 state, its:        M0 + 2HCl  ----> MCl2 + H2O

                                  x+16                    x+72

 so, it shld be 3/(x+16)  = 5/(x+72) 

 which gives x = 66.5

so, the metal is Zinc

its eq. wt = 33.25
