we also haveokay. Plus one into oxygen, we also haveokay. Plus one into oxygen, we also havehere how big is it.here how big is it.here how big is it.16th atomic number of oxygen is airtel mass number - 16,16th atomic number of oxygen is airtel mass number - 16,16th atomic number of oxygen is airtel mass number - 16,so here you have given meat number but ifso here you have given meat number but ifso here you have given meat number but ifyou have to point it molecular mass,you have to point it molecular mass,you have to point it molecular mass,okay now we will take its sixteenth here.okay now we will take its sixteenth here.okay now we will take its sixteenth here.202 Enter 600 Back How much did the total become? 800202 Enter 600 Back How much did the total become? 800202 Enter 600 Back How much did the total become? 800Why do we write that these are units of molecular mass?Why do we write that these are units of molecular mass?Okay, what have we calculated now?Okay, what have we calculated now?Okay, what have we calculated now?Molecular mass of molecule two. We haveMolecular mass of molecule two. We haveMolecular mass of molecule two. We havemasterminded the molecule with this policy. Do youmasterminded the molecule with this policy.
