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.
Bohr suggested, that there are definitive shells of particular energy and angular momentum in which an electron can revolve. It was not in Rutherford's model
The new volume be if the pressure inside the balloon was reduced to 58kpa is 2.58 L.
<h3>What is ideal gas equation?</h3>
Ideal gas equation PV=nRT gives idea about the behavior of gases at different conditions and for this question the equation becomes:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 115.3 kpa
V₁ = initial volume = 1.3 L
P₂ = final pressure = 58 kpa
V₂ = final volume = ?
On putting all these values in the above equation, we get
V₂ = (115.3)(1.3) / (58) = 2.58 L
Hence resultant volume of gas is 2.58 L.
