Question

estimate the speed of sound in air at standard temperature and pressure the mass of 1 mole of air is 29.0 x 10 ^- 3 kg.​

Answer 1

It's help u...

For air, the adiabatic constant γ = 1.4 and the average molecular mass for dry air is 1 mole of air is 29.0 x 10-3 kg. Temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (14.504psi, 0.987 atm, 1 bar).

plz mark me

Answer 2

hello,here is your answer:

*****We know that 1 mole of any gas occuptes 22.4 litres

***** at STP. Therefore, density Answ of atr at STP is (mass of one mole of air)/

***** (volume of one mole of air at STP) 29.0 10 3 kg 22.4 10 m -1.29 kg m According to Newton's formula for the speed.

hope my answer helps you friend :)
