Answer ; The correct answer is : 346 m/s .
Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .
Speed of sounds depends on factors like medium , density , temperature etc .
Effect of Temperature on speed of sounds :
When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .
The speed of sounds at 0⁰C is 331
The relation between speed of sound and temperature is given as :
Given : Temperature = 25 ⁰ C
Plugging values in formula =>
Given volume of hydrogen = 25 L
Standard temperature = 273 K
Standard pressure = 1 atm
R is gas constant = 0.08206 L.atm/(mol.K)
Plugging in the values in ideal gas equation and solving for moles of hydrogen (n):
n = 1.12 mol
1.66x10^-15 mol. It's not a full mole. You take the number of molecules and use dimensional analysis to figure it out.

First oil well in the United States, built in 1859 by Edwin L. Drake, Titusville, Pennsylvania.
Definition: Momentum, product of the mass of a particle and its velocity.
Equation: p=mv (momentum= mass multiplied by velocity)
P: momentum
M: mass
V: velocity
