The mass of the air in the railroad car is 224.54 pounds.
To get the mass of the air (pounds) that is in the railroad car,
first, we calculate the volume of the air.
Formula:
- V = lwh............ equation 1
Where
- V = Volume of the air in the railroad
- l = Length of the railroad
- w = width of the railroad
- h = height of the railroad.
From the question,
Given:
- l = 12 feet
- w = 8 feet
- h = 25 feet
Substitute these values into equation 1
- V = 12(8)(25)
- V = 2400 ft³
- V = (2400×28.3168)
- V = 67960.32 L
What is mass?
Mass can be defined as the quantity of matter contained in a body. The s.i unit of mass is kilogram (kg)
Finally, we use the formula below to calculate the mass of air in pounds.
- m = DV............ Equation 2
Where
- D = Density of air = 1.5 g/L
- V = 67960.32 L
Substitute these values into equation 2
- m = (1.5×67960.32)
- m = 101940.48 g
- m = (101940.48/454) pounds
- m = 224.54 pounds.
Hence, The mass of the air in the railroad car is 224.54 pounds.
