Find the volume that takes 1.5 mol of ozone.

1. The volume of gases is found by the formula:

V = n * Vm, where V is the volume, n is the amount of substance (in moles), Vm is the molar volume of the gas.

2. Vm = 22.4 dm3 (constant), n = 1.5 (by condition).

2. Substitute the values into the formula:

V (ozone) = 1.5 * 22.4 = 33.6 dm3.

Answer: At n.u. 1.5 mol of ozone will take 33.6 dm3.
