Answer:
V= 0.147 L
Explanation:
This is simply the application of combined gas law twice, to find the unknowns.
Combined gas law states that: 
P= pressure of air
V= volume of air
n= moles of air
R= Universal gas constant ( 0.08205 L atm mol⁻¹ K⁻¹)
T= Absolute temperature in kelvin.
Now, applying the same gas law at 483K and substituting for n
V= 
V= 0.147 L
Answer: The percentage composition of hydrogen in the given compound is 15%.
Explanation:
To calculate the percentage composition of hydrogen in a compound, we use the formula:
Where,
Mass of hydrogen = 41.4 grams
Mass of compound = 276 grams
Putting values in above equation, we get:
Percentage composition of hydrogen in a given compound = 15%
