D312

Correct answer

A. 402

Step-by-step solution

Mass of one mol gas, m =22.4 10⁻³ ~kg Specific heat ratio, r =1.6 Pressure at STP, P =1.01 10^5 ~N / m ^2 Volume at STP, V =22.4 10⁻³ ~L Speed of sound is given as v = P = PV M Substitute necessary values v = 1.6 1.01 10^5 22.4 10⁻³ 22.4 10⁻³ v =4.02 10^2 ~m / s
