2.065 pounds per cubic yard
The weight of air at sea level is approximately 0.075 pounds per cubic foot. One cubic yard is equal to 27 cubic feet, so the weight of air per cubic yard at sea level would be approximately 2.025 pounds.
That depends on what objects or substances are in the cubic yard. -- If it's full of air, it weighs about 2.15 pounds (if there's no other air around it). -- If it's full of water, it weighs about 1,688 pounds. -- If it's full of gold, it weighs about 32,063 pounds. -- If it's an empty cubic yard, it has no weight at all.

The mass of the air would be 984g at 25C (temperature also has an effect).
If you take the average weight of all of the molecules in one cubic foot of air and add them together you reach 0.0807 pounds. This number can fluctuate with temperature and variations in the composition in the air.

The weight that 1 cubic foot of air can support depends on the density of the air. At sea level and room temperature, 1 cubic foot of air can support approximately 0.08 pounds. However, this value can vary based on factors such as altitude and temperature.
The weight of air is about 1.2 kg/m^3 at sea level. That means for each cubic meter of air, it weighs approximately 1.2 kilograms.
At sea level and 15 deg C, the weight of a cubic metre of air is approx 11.0 Newtons.
There are 27 cubic feet in 1 cubic yard. So, the air conditioning system can circulate 290 / 27 = 10.74 cubic yards of air per minute.
AnswerWell,1 cubic yard of water at 68 degrees Fahrenheit weighs 1,681.297 pounds.There are 27 cubic feet in 1 cubic yard, and there are 7.48 gallons in each cubic foot, and 1 gallon of water at 68 degrees weighs 8.3249.The Math: 27 x 7.48 x 8.3249 = 1,681.297 pounds.The density of water changes ever so slightly depending on it's temperature.
