A dry gas mixture (60% oxygen, 40% helium, by volume) is at 94 °C and 3.4 atm. Moisture is then added. The properties at the final state are 94 °C, 3.4 atm, and 20% relative humidity. Determine (a) the dew-point tempera- ture (°C), (b) the molar composition of the moist gas, and (c) the humidity ratio.

Hello, I need help with the following question

A dry gas mixture (60% oxygen, 40% helium, by volume) is at 94 °C and
3.4 atm. Moisture is then added. The properties at the final state are 94 °C,
3.4 atm, and 20% relative humidity. Determine (a) the dew-point tempera-
ture (°C), (b) the molar composition of the moist gas, and (c) the
humidity ratio.
