heat capacity ratio of argon

I need help to calculate the uncertainty, 95% Error propagation for the sound velocity and for the heat capacity ratio for this experiment.

everything already calculated I just need help for what I mentioned.

heat capacity ratio of Argon, co2 and N2

CO2 trial 1 and 2

N2 trial 1 and 2

bo more data needed
