A sound wave travels through a column of carbon monoxide at STP. Assuming a density of rho = 1.25 kg/m3 and a bulk modulus of β = 1.42 ✕ 105 Pa, what is the approximate speed (in m/s) of the sound wave?

v = 337.04m/s

Explanation:

In order to calculate the speed of sound for the case of a carbon monoxide medium, you use the following formula:

      (1)

v: speed of sound

β: bulk modulus = 1.412*10^5 Pa

ρ: density of the column of carbon monoxide = 1.25 kg/m^3

You replace the values of the parameters in the equation (1):

The speed of the sound in the column of carbon monoxide is 337.04 m/s

15.3 cos 65 degrees trig

0.11 m/s and 0.28 m/s should be correct
