What is the ratio of the velocity of sound in helium gas to that in air at the same pressure and temperature? Molar mass of helium is 0.004 kg. = 1.66. On the basis of your answer, can you explain why you will sound funny if you happen to inhale helium gas and speak?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

its c its is a mixture of gases
