Homework Statement

Estimate to 1 significant figure the total # of air molecules in this room (l=20ft, w=14ft, H= 8ft) Find molecules/room

Homework Equations

1 mole = 22.4 liters
6.02 x 10^23 molecules = 1 mole

The Attempt at a Solution

volume of room = 2240 ft^3 or approx 683 m^3

6.02x10^23 Molecules / 1 mole x 1 mole/ 22.41 liters = 6.02 x10^23 molecules/ 22.41 liters... I am stuck here. how do i figure out how many liters are in the room?
