complete the complex dimensional analysis problem to determine the price of one atom of aluminum. A 20cm X 20cm square of aluminum has a mass of 1.50g. A box of aluminum costs $1.29 and the area of foil in the box is 2.32m^2.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
