I will show you a method to find a velocity of anything:-
Find average velocity when acceleration is constant.
Set up an equation with position and time instead.
Find the distance between the start and end points.
Calculate the change in time.
Divide the total displacement by the total time.
Solve problems in two dimensions.
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
I think it is C. coefficients but I don't know what subscripts are
