At least google stuff like this before posting it (and maybe include a reference) because this is unequivocally wrong. Speed of sound in a gas is calculated with the Newton-Laplace equation [1] which refers to K, the bulk modulus which is derived from the pressure and the adiabatic constant for ideal gases. It also involves rho, the density of the medium which is why gases and non-gaseous fluids have very different results.
