Instability of an atoms nucleus can result from an excess of either neutrons or protons . So neutrons and protons .
Molar mass of sodium=23g
2 mole sodium gives 2 g H2
i.e 46g sodium gives 2g H2
so 65.4g will give=2.84g H2
now no. of molecules = 2.8/2*avogadros number
You kind of need to show more, but the independent variable would be something that you are changing to then measure the reaction, like the time left in for example.
Answer:
