With M and X unknown and the following formules and datas I have to find the molecular weigth of M and X.
2MXO₃ =   3O₂+       2MX
2.451g      0.9600g   1.491g

2MX  + 2AgNO₃ = 2AgX  + 2MNO₃
                         2.869g

I know that the quantity which I begin in the second formula is 1.491(the same that the final of the first formula), but I can't find another data for work. I tried to found the quantity of Ag, but I don't Know the total mol .A hint please

Well, there's one thing you do know. How many moles of O₂ is 0.9600g?
