There are several pieces of additional information you need to go from units of volume/time to units of force/time.
For gasses, temperature and pressure matter. Air is mostly nitrogen and oxygen. These have atomic masses of 14 and 16 respectively. Both form diatomic molecules, so air is a mixture of gasses with molecular masses of 28 and 32. Since there is more nitrogen than oxygen, I'm going to say "air" has a molecular mass of 29. Close enough given your precision of "0.08".
At Standard Temperature and Pressure (STP; 1 atm, 0 °C), a mole of ideal gas occupies 22.4 liters. Let's say you're really asking about 21 °C. That's 294 °K as apposed to 273 °K at STP. The volume will therefore be (22.4 l)(294 °K)/(273 °K) = 24.1 l. Since that's one mole, it has a mass of 29 g. Put another way, we've decided the density of your "air" is 29 g/24.1 l.
There are 1000 liters in a cubic meter, so your 0.08 cubic meters is 80 liters, which has a mass of 96.2 g. There are 60 minutes in one hour, so we can compute the mass flow rate in your final time units, which is 5.77 kg/h.
The remaining problem is to convert kg to pounds. Kg is a unit of mass, and pounds is a unit of weight. The conversion depends on gravity. You didn't say if whether this is on the surface of the earth, on the internal space station, or somewhere else. I'll assume the surface of the earth where 1 kg of mass weighs about 2.2 pounds. (5.77 kg)(2.2 lb/kg) = 13 lb.
The final answer is therefore 0.08 cubic meter per minute of air at 1 atmosphere, 21 °C, on the surface of the earth is about 13 pounds/hour.
