Answer:
Volume of air is [tex]60[/tex] cubic meter
Mass of air is [tex]72.246[/tex] Kilogram
Explanation:
As air occupies the volume of the container in which it is kept. The volume of air here in this case will be equal to the volume of the room.
Volume of the room = length * breadth * height
Volume of the room = [tex]4*5*3 = 60[/tex] cubic meter.
Volume of air is also [tex]60[/tex] cubic meter.
Density of air at 20 degrees C [tex]= 1.2041[/tex] kg/cu.m
Mass of air
Volume * density
[tex]60 * 1.2041 = 72.246[/tex] kilogram
Volume of air is [tex]60[/tex] cubic meter
Mass of air is [tex]72.246[/tex] Kilogram
