A gas containing 80% CH, and 20% He is sent through a quartz diffusion tube (see Figure P8.8) to recover the helium. Twenty percent by weight of the original gas is recovered, and its composition is 50% He. Calculate the composition of the waste gas if 100 kg moles of gas are processed per minute. 80% CH. 20% He - Waste gas 50% He recovered gas Figure P8.8
