Answer:
Baking soda = No. of atoms are 1 sodium + 1 Hydrogen + 1 carbon + 3 oxygens = 6 atoms per molecule.
Solution :
Molar mass of
is :
M = 6×12 + 6×1 g
M = 78 g
78 gram of
contains
molecules.
So, 89.5 gram of
contains :

Now, from the formula we can see that one molecule of
contains 2 hydrogen atom . So, number of hydrogen atom are :

Hence, this is the required solution.
Yes that’s correct it is B
