1. 1.00 kg of CH4, 6.30 kg of O2, and 13.2 kg of N2 are combined to form a gas mixture. Find the molecular mass of the mixture.

2. Ammonia gas is flowing in a tube whose cross-sectional area is 1.00 ft2 . The density of the ammonia is 0.100 lbm/ft3 . At some point in the system, CO2 is added at a rate of 1.00 × 10-3 lbm/h in a steady flow process. At a point further downstream, a detector indicates that the concentration of CO2 on a mass basis is 1.00 × 10-3 %. Determine the inlet velocity of the ammonia.
